WebThe atomic number of nickel is 28. The atomic number is the number of protons. That is, the number of protons in nickel is twenty-eight. Electrons equal to protons are located in a … Web9 aug. 2000 · The isotopes of hydrogen have, respectively, mass numbers of one, two, and three. Their nuclear symbols are therefore 1 H, 2 H, and 3 H. The atoms of these isotopes have one electron to balance the charge of the one proton. Since chemistry depends on the interactions of protons with electrons, the chemical properties of the … The atomic number of an element is equal to the number of protons and electrons in that element. Therefore, a nickel atom has twenty-eight protons and twenty-eight electrons. The number of neutrons in an atom can be determined by the difference between the atomic mass and the number of protons.
