Can two elements have same number of neutrons?
Atoms from two different elements may have the same number of neutrons
, but never the same number of protons. The number of protons is unique to the element and represents the atomic number.
Do all elements have the same number of neutrons?
The number of neutrons can be different, even in atoms of the same element
. Atoms of the same element that contain the same number of protons, but different numbers of neutrons, are known as isotopes.
Can two elements have same number of electrons?
Isotopes have same atomic number bu different mass numbers.
Elements that have same number of electrons and protons will have same atomic number
. If they have different number of neutrons, they will have different mass numbers. Thus, these two elements with same atomic number bu different mass numbers will be isotopes.
Can two elements have the same protons?
Since
no two element can have same number of protons
, thus atomic number cannot be same and also atomic number can also be called an unique ID of an element.
What has the same number of neutrons?
Isotones
: The nuclei having an equal number of neutrons are called isotones.
Can two elements have the same mass number?
Different isotopes of the same element cannot have the same mass number
, but isotopes of different elements often do have the same mass number, e.g., carbon-14 (6 protons and 8 neutrons) and nitrogen-14 (7 protons and 7 neutrons).
Can elements have the same electrons?
Answer: False.
Elements in the same GROUP have similar electron configurations
.
When two elements have same number of protons and different number of neutrons they have?
Atoms of the same element, containing the same number of protons, but different numbers of neutrons, are known as
isotopes
. Isotopes of any given element all contain the same number of protons, so they have the same atomic number (for example, the atomic number of helium is always 2).
Do atoms have the same number of protons and neutrons?
Atoms always have an equal number of protons and electrons, and
the number of protons and neutrons is usually the same as well
. Adding a proton to an atom makes a new element, while adding a neutron makes an isotope, or heavier version, of that atom.
Do elements have same number of protons and electrons?
The number of electrons in a neutral atom is equal to the number of protons
.
Which two elements have same number of protons electrons and neutrons?
Helium and Carbon
are two elements with same number of protons and neutrons.
Do all atoms have neutrons?
All elements have atoms with neutrons except for one
. A normal hydrogen (H) atom does not have any neutrons in its tiny nucleus. That tiny little atom (the tiniest of all) has only one electron and one proton. You can take away the electron and make an ion, but you can't take away any neutrons.
Are atoms of different elements which have same number of neutrons but different mass number?
Two atoms with the same atomic number, but different mass numbers (same number of protons, different number of neutrons), are called
isotopes, or isotopic nuclides
. Having different numbers of neutrons changes the mass of these atoms, so isotopes have slight variations in their physical and chemical behavior.
When 2 atoms have the same atomic number they are classified as the same?
Atoms of the same element having the same atomic number but different mass are called
isotopes
.
Do any elements have the same number of protons?
All atoms of an element have the same number of protons
, and every element has a different number of protons in its atoms. For example, all helium atoms have two protons, and no other elements have atoms with two protons.
Do all elements have the same atomic number?
Explanation:
No, because each element has its own specific property, BUT certain elements have similar properties, like elements in the same family
. The atomic number is associated to the element's composition for one atom, in which the atomic number = number of protons in the atom with a neutral charge.
Can you have 0 neutrons?
There is only one stable atom that does not have neutrons
. It is an isotope of the element hydrogen called protium. Protium, which contains a single proton and a single electron, is the simplest atom.
How can you tell if two elements are the same?
Two different elements have similar chemical properties
when they have the same number of valence electrons in their outermost energy level
. Elements in the same column of the Periodic Table have similar chemical properties.
Are all electrons identical?
Every electron in the universe has exactly the same mass, exactly the same charge
, and if you think about it, there's no reason why they'd have to be. In 1940, physicist John Wheeler came up with a novel new theory that might explain why all electrons are identical.
Can two atoms have the same number of electron but different number of neutron?
Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons
. The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have different masses.
Should protons equal neutrons?
For most of the 16 lightest elements (up to oxygen)
the number of neutrons is equal to the number of protons
.
Are protons and electrons equal?
The number of electrons on a neutral atom is equal to the number of protons in the nucleus of the atom
.
What element has an equal number of protons and neutrons?
| Name | Hydrogen | Protons | 1 | Neutrons | 0 | Electrons | 1 | Atomic Number (Z) | 1 |
|---|
Does number of neutrons change?
The number of neutrons can be different, even in atoms of the same element
. Atoms of the same element that contain the same number of protons, but different numbers of neutrons, are known as isotopes.
Why does hydrogen not have a neutron?
Hydrogen does not contain neutron, because
its nucleus is smallest in size which can not accommodate any heavier neutron
. It also makes hydrogen atom unstable in nature.
Which element does not contain any neutrons?
Hydrogen
is the only element that does not contain any neutrons in its nucleus.
What do you mean by isotones?
isotone,
any of two or more species of atoms or nuclei that have the same number of neutrons
. Thus, chlorine-37 and potassium-39 are isotones, because the nucleus of this species of chlorine consists of 17 protons and 20 neutrons, whereas the nucleus of this species of potassium contains 19 protons and 20 neutrons.
Why do all atoms of an element have the same atomic number?
Atoms themselves are composed of protons, neutrons, and electrons. Each element has its own atomic number, which is
equal to the number of protons in its nucleus
. Isotopes of an element contain different numbers of neutrons.
What are element that having the same atomic number but different mass number is?
Do all elements have the same number of protons?
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.
All atoms of an element have the same number of protons
, and every element has a different number of protons in its atoms.
Do all elements have the same number of electrons?
Atoms do not always contain the same number of electrons and protons
, although this state is common. 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).
