What is the atomic mass of hafnium if, out of every 100 atoms, 5 have a mass of 176, 19 have a mass Cations are positive ions formed by losing electrons, while anions are negative ions formed by gaining electrons. The number of protons determines an element's atomic number, which scientists use to distinguish one element from another.the number of neutrons is variable, resulting in isotopes, which are different forms of the same atom that vary only in the number of neutrons they possess.
