An atom has 10 protons, 10 neutrons and 10 electrons. An isotope of this atom may contain 11 neutrons.
The chemical properties of atoms depend on the types and number of subatomic particles they contain.
We have an atom with 10 protons, 10 neutrons and 10 electrons. The number of protons determines the identity of the atom. The atom with 10 protons is neon.
We want to find an isotope of neon. Isotopes are atoms of the same element that differ in the number of neutrons. Thus, an isotope of this atom may contain 11 neutrons rather than 10.
