When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na + ) and a chloride anion (Cl
What happens to the electrons when sodium and chlorine atoms react?
If sodium metal and chlorine gas mix under the right conditions, they will form salt. The sodium loses an electron, and the chlorine gains that electron . This reaction is highly favorable because of the electrostatic attraction between the particles.
What happens to an atom of chlorine if it gains an electron?
Again, it is more energy-efficient for chlorine to gain one electron than to lose seven. Therefore, it tends to gain an electron to create an ion with 17 protons, 17 neutrons, and 18 electrons , giving it a net negative (–1) charge. It is now referred to as a chloride ion.
When a sodium atom transfers an electron to a chlorine atom?
Ionic bonds are formed when two atoms are held together by an attraction between ions. Sodium transfers a negatively charged electron over to chlorine. The result is sodium having a positive charge (Na+) and chlorine now having a negative charge (Cl-).
What happens when sodium and chlorine atoms react to form sodium chloride?
Sodium and chloride form an ionic bond . Therefore the sodium atom loses one electron from its outer shell and the chlorine atom gains one electron. As this happens, the electron is transferred from the sodium atom to the chloride atom and so both atoms become ionic and have a full outer shell.
What happens when sodium and chlorine atoms form sodium chloride?
When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na + ) and a chloride anion (Cl – ), both ions have complete valence shells, and are energetically more stable . The reaction is extremely exothermic, producing a bright yellow light and a great deal of heat energy.
When a sodium atom loses an electron what does it become?
2 Answers By Expert Tutors. It reaches the nearest “noble gas” configuration, albeit as the cation Na+. Sodium will let that electron go as soon as it can, which is why it generally forms ionic compounds such as NaCl. When sodium atom loses an electron from its outer energy shell, it becomes Na + ion .
What happens when a chlorine atom gains an electron in its outer energy shell apex?
What happens when a chlorine atom gains an electron in its outer energy shell? It becomes a negative ion .
What is chlorine atom?
What is a chlorine atom? Chlorine is an atom that has 17 protons and usually either 18 or 20 neutrons in its nucleus and 17 electrons circling around its nucleus.
What do you see when sodium reacts with chlorine?
Sodium and chlorine react vigorously when heated, giving an orange flame and clouds of white sodium chloride .
What is the reason why atoms of sodium and chlorine attract each other in a salt crystal?
Sodium and chlorine atoms are near each other. The protons of the two atoms attract the electrons of the other atom . The thicker arrow shows that chlorine has a stronger attraction for electrons than sodium has.
How do sodium and chlorine atoms form the ions in sodium chloride and how the ions are arranged in the solid sodium chloride?
Sodium chloride is an ionic compound. It is made of sodium ions which have lost an electron to become positively charged (Na+) and chloride ions which have gained an electron to become negatively charged (Cl-).
How does sodium and chlorine form an ionic bond?
Ionic Bonds. ... It is easiest for sodium to lose its electron and form a +1 ion, and for chlorine to gain an electron, forming a -1 ion. If sodium can transfer it’s “spare” electron to chlorine (as shown above), both atoms will satisfy their full outer shell requirements, and an ionic bond will be formed.
How does a chlorine atom form a chloride ion?
Chlorine, Cl
It has seven electrons in its outer shell. It gains an electron from another atom in reactions , forming a chloride ion, Cl – .
When a sodium atom reacts with a chlorine atom to form a compound the electron configuration?
Explanation: During this reaction, the sodium loses one electron on its outer shell which then gives it the electron configuration of neon (2-8) and the chlorine gains one electron on its outer shell which then gives it the electron configuration of argon (2-8-8) .
What happens when atoms bond together?
A chemical bond is formed when atoms are held together by attractive forces . This attraction occurs when electrons are shared between atoms, or when electrons are exchanged between the atoms that are involved in the bond. ... In other words one atom gains an electron while the other loses an electron.
What happens when a molecule of sodium chloride is formed?
Sodium chloride is formed when sodium atoms interact with chlorine atoms . When this occurs, sodium will donate an electron (which is a negatively-charged particle) to chlorine. This makes sodium slightly positive and chlorine slightly negative.
When a chlorine atom forms an ion its radius?
When an atom of chlorine forms a chloride ion, it gains an electron to become an anion . The chloride ion has a bigger ionic radius than its parent atom, chlorine. B. The chlorine atom gains an electron, and its radius becomes larger.
When an atom gains an electron in its outer shell it becomes?
An atom that loses one or more valence electrons to become a positively charged ion is known as a cation, while an atom that gains electrons and becomes negatively charged is known as an anion .
What happens when an atom that has lost an electron comes in contact with an atom?
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).
How many atoms are in a chlorine atom?
Chlorine molecules are composed of two atoms (Cl 2 ).
How are chlorine atoms different?
The different types of chlorine are called isotopes of chlorine . Isotopes are forms of an element that have the same number of protons but different numbers of neutrons. ... They have the same mass number, A, but different atomic number, Z, and different chemical symbol – they are not the same element.
What happens to the sodium and chlorine atoms after pouring them into the water?
Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together . After the salt compounds are pulled apart, the sodium and chloride atoms are surrounded by water molecules, as this diagram shows. Once this happens, the salt is dissolved, resulting in a homogeneous solution.
How does a sodium atom form a sodium ion?
A sodium atom has one electron in the outer shell. A chlorine atom seven electrons in the outer shell. A sodium atom loses an electron to a chlorine atom . The sodium atom becomes a positive sodium ion.
What kinds of ions do a sodium atom and a chlorine atom become when a valence electron is transferred from one to the other?
What kind of ions do a sodium atom and a chlorine atom become when a valence electron is transferred from one to the other? the sodium atom becomes a positive ion and the chlorine atom becomes neg .
When do atoms form ionic bonds?
Ionic bonds form when a nonmetal and a metal exchange electrons , while covalent bonds form when electrons are shared between two nonmetals. An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions.
What happens when chlorine forms an ion?
What happens when chlorine forms an ion? It gains an electron and has an octet in its outer shell .
Does sodium chloride contain ions or atoms?
Sodium chloride (chemical formula NaCl), known as table salt, rock salt, sea salt, and the mineral halite, is an ionic compound consisting of cube-shaped crystals composed of the elements sodium and chlorine. It is responsible for the saltiness of the world’s oceans.
What ion would chlorine atom form?
A neutral chlorine atom, for example, contains 17 protons and 17 electrons. By adding one more electron we get a negatively charged Cl – ion with a net charge of -1. The gain or loss of electrons by an atom to form negative or positive ions has an enormous impact on the chemical and physical properties of the atom.
What causes an ionic bond to form between sodium and chlorine quizlet?
In ionic compounds, atoms gain or lose electrons to form ions. ... When the atoms of each element first come together, both are electrically neutral. When they get close enough, an electron transfers from the sodium to the chlorine. This makes a positive sodium ion, Na+, and a negative chloride ion, Cl-.
Why do atoms form ionic bonds?
Formation of ionic bond
An ionic bond can be formed after two or more atoms loss or gain electrons to form an ion . Ionic bonds occur between metals, losing electrons, and nonmetals, gaining electrons. Ions with opposite charges will attract one another creating an ionic bond.
