Question

There are three known forms of hydrogen. These forms are called A. Isotopes, B. Copies, C. Ions, of each other. Each of these forms will have the same number of A. Protons, B. Neutrons, C. Electron, but different numbers of A. Protons, B. Neutrons, C. Electrons, in their nuclei.

Answer 1

There are three known forms of hydrogen. These forms are called Isotopes (option A) of each other.

Each of these forms will have the same number of Protons (Option A)

but different numbers of Neutrons (Option B) in their nuclei.
