They are called isotopes and the difference between different isotopes of one type of element is the amount of neutrons each have.
The atom of an element of sodium is called a sodium atom. It consists of a nucleus containing 11 protons surrounded by a cloud of 11 electrons.
It's still an atom. It would be a different isotope of the same element.
Isotopes of elements have different atomic mass'.
Atomic number and it also tells the number of protons and electrons in an atom it is on top of the element symbol.
Elements are substances such as Hydrogen. It has 1 Proton, and 0-2 neutrons. Since the number of neutrons can vary, we call each form of Hydrogen an isotope. A hydrogen with no neutrons and a hydrogen with 1 nuetron are both still Hydrogens. We simply call one the Hydrogen-1 Isotope. An isotope is just a variation of an element as the element can have different numbers of neutrons. All isotopes of an element have the same number of protons, else itd be an isotope of another element.
A substance that only contains one kind of atom is called an element.
An atom of a different element.
You call a substance with only one type of atom, an element.

The atom of an element of sodium is called a sodium atom. It consists of a nucleus containing 11 protons surrounded by a cloud of 11 electrons.
The smallest particle of matter is called an atom. It is the basic unit of a chemical element and retains the properties of that element.
It's still an atom. It would be a different isotope of the same element.
