When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral .
Is the number of electrons always equal to the number of protons?
Heavier atoms tend to have more neutrons than protons, but the number of electrons in an atom is always equal to the number of protons . So an atom as a whole is electrically neutral. When one or more electrons is stripped away from an atom, it becomes positively charged.
What is it called when the number of protons and electrons are not equal?
An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule.
What are positive ions called?
The atom that has lost an electron becomes a positively charged ion (called a cation ), while the atom that picks up the extra electron becomes a negatively charged ion (called an anion).
Are there always equal number of protons and neutrons?
Atoms of a particular element must have the same number of protons but can have different numbers of neutrons. When an element has different variants that, while all having the same number of protons, have differing numbers of neutrons, these variants are called isotopes.
What is it called when an atom loses electrons?
When an atom loses electrons, it is called a Cation and has a positive charge. What are cations and anions? Cations are positively charged ions.
What name is given to the part of the atom where the protons and neutrons are?
The protons and neutrons are found in the nucleus at the centre of the atom. The nucleus is very much smaller than the atom as a whole. The electrons are arranged in shells around the nucleus.
What particle determines the name of the element?
Explanation: The identity of the element is determined by the number of protons , which are positively charged, massive nuclear particles. The number of protons in a nucleus is given by Z , the atomic number.
What is ion slang?
This ion means “ I don’t .” It is a spelling based on the colloquial pronunciation of I don’t, especially in Black English. Try this: say “I don’t know” fast and casually. You’re probably saying something that actually sounds like ion–oh. This is actually how we talk, people. Ion wanna compete I just wanna win.
What are positive and negative ions called?
ion, any atom or group of atoms that bears one or more positive or negative electrical charges. Positively charged ions are called cations ; negatively charged ions, anions.
Why is there an equal number of protons and electrons?
An electron is a negatively charged particle and a proton is a positively charged particle. As negative charged attracts the positive charged and vice versa, both electron and proton stays together so that overall charge is zero / neutral. Thus an atom always has equal electrons and protons to remain neutral .
Why is the atomic number equal to protons and electrons?
An atom contains equal numbers of protons and electrons . Since protons and electrons have equal and opposite charges , this means that atoms are neutral overall .
Why are positive ions called cations?
Remember, cations are positive ions—they are positively charged because they have lost one or more electrons and therefore have more protons than electrons .
What does it mean when something loses electrons?
Atoms that lose electrons acquire a positive charge as a result because they are left with fewer negatively charged electrons to balance the positive charges of the protons in the nucleus. Positively charged ions are called cations.
What is it called when an atom gains or loses the charged particle that results a molecule?
When an atom gains or loses electrons, the charged particle that results is called an ion . ... The smallest particle of an ionic compound is a molecule.
When an atom loses an electron what is its quizlet?
When an atom loses an electron, it loses a negative charge and becomes a positive ion .
What is the name given to the central portion of an atom?
The central part of an atom, which makes up most of its mass, is called the nucleus ; this is surrounded by an ‘electron cloud’, which largely determines how the atom reacts with other atoms or molecules. The nucleus of an atom is made up of building blocks called protons and neutrons.
What particle determines the atomic number?
Atoms of each element contain a characteristic number of protons . In fact, the number of protons determines what atom we are looking at (e.g., all atoms with six protons are carbon atoms); the number of protons in an atom is called the atomic number.
What is name of the part where electrons are located?
The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).
What is the name given to the Centre of the atom?
The nucleus is the positively charged centre of an atom and contains most of its mass. It is composed of protons, which have a positive charge, and neutrons, which have no charge.
What is a rule for what determines the name of the element you build what is it that determines the element?
Atomic number : The number of protons in an atom is referred to as the atomic number of that element. The number of protons defines what element it is and also determines the chemical behavior of the element. For example, carbon atoms have six protons, hydrogen atoms have one, and oxygen atoms have eight.
What is the number protons called?
The number of protons in an atom is called its atomic number (Z) . This number is very important because it is unique for atoms of a given element.
What does ION mean on Tik Tok?
What does ion mean? ‘Ion’ is often used as a contraction of ‘I don’t,’ however, when used as the acronym ‘ION,’ it can also mean ‘ In Other News . ‘ However, the former meaning is generally more common on social media platforms like Twitter and TikTok.
What does FW mean on Snapchat?
Summary of Key Points. “ F*ck With ” is the most common definition for FW on Snapchat, WhatsApp, Facebook, Twitter, Instagram, and TikTok. FW. Definition: F*ck With.
What does Lon mean in texting?
| Acronym Definition | LON Local Order Number | LON Learning Online Network | LON Local Operating Network | LON Labyrinth of Nightmare (Yu-Gi-Oh cards) |

What type of ions have names ending in?
Polyatomic positive ions often have common names ending with the suffix -onium. Negative ions that consist of a single atom are named by adding the suffix -ide to the stem of the name of the element.
Why positive ion is called cation and negative ion is called anion?
positive ions are called cations because is losses electrons and negative ions are called anions because is gains electron .
Do cations have more protons than electrons?
A cation has more protons than electrons , consequently giving it a net positive charge.
What is cation chemistry?
cation, atom or group of atoms that bears a positive electric charge .
When an atom is charged it is called an ion how many electrons are in o2?
In an oxygen ion with a 2− charge, the number of protons is still 8, but the number of electrons is 10 . This results in the oxygen ion having an octet (8) of valence electrons.
What is a positive ion what is a negative ion quizlet?
What is a negative ion? A positive ion is a neutral atom that has lost one or more electrons . A negative ion is a neutral atom that has gained one or more electrons.
What type of atoms have the same number of electrons and protons?
| Name | Hydrogen | Protons | 1 | Neutrons | 0 | Electrons | 1 | Atomic Number (Z) | 1 |

What do you call the attraction between the nucleus and the electron?
A mutual electrical attraction between the nuclei and valence electrons of different atoms that binds the atoms together is called a chemical bond ....
Is atomic number equal to number of electrons?
The atomic number uniquely identifies a chemical element. It is identical to the charge number of the nucleus. In an uncharged atom, the atomic number is also equal to the number of electrons .
Is atomic number equal to electrons?
The number of protons, neutrons, and electrons in an atom can be determined from a set of simple rules. The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons .
The number of protons determines an element’s atomic number and is used to distinguish one element from another. ... Together, the number of protons and the number of neutrons determine an element’s mass number.
Why is reduction called reduction?
Reduction is known as reduction because it refers to addition of electrons , which leads to a reduction in oxidation number of the atom. lol! its called reduction because the opposite of reduction is called oxidation in which oxygen molecule is added in the compound. and when the reducing of that oxygen takes place.
Why is electron loss called oxidation?
In the early days of chemistry, oxidation was defined as a gain of oxygen atoms. ... the Mg was said to be oxidized because it gained an oxygen atom. Eventually, chemists realized that the reaction involved a transfer of electrons from Mg to O .
When a substance is reduced it is called?
Substances that have the ability to reduce other substances (cause them to gain electrons) are said to be reductive or reducing and are known as reducing agents , reductants, or reducers. The reductant (reducing agent) transfers electrons to another substance and is thus itself oxidized.
