For 60Ni2+, identify each of the followingMass Number

Question

BlackTom AI · Accepted Answer

First, recall what the mass number represents in nuclear notation. The mass number (A) is the total number of protons and neutrons in the nucleus.
Second, identify the atomic number (Z) from the element symbol or standard information. Nickel (Ni) has an atomic number Z = 28, which means 28 protons reside in the nucleus.
Third, use the information given in the isotope notation. The notation 60Ni2+ indicates a mass number A of 60, and a charge state of +2, which implies the ion has two fewer electrons than the neutral atom, but does not change the count of nucleons (protons + neutrons).
Fourth, verify consistency: if A is 60 and Z is 28, then the number of neutrons N is A − Z = 60 − 28 = 32. This aligns with typical isotope labeling where mass number reflects total nucleons, independent of electron count.
Fifth, address potential confusion: the superscript or charge (2+ in Ni2+) affects electron configuration but not the nucleus’s nucleon count, so it does not alter the mass number value.
If you were asked to provide the mass number for this isotope, you would report the total nucleons, which correspond to A = 60; the nucleus contains 28 protons and 32 neutrons, totaling 60 nucleons.
