Platinum Element | The Practical Element Platinum | ChemTalk
Platinum, because it has unpaired electrons and resides in the D block, is a transition metal. Platinum has five stable isotopes ( 192 Pt, 194 Pt, 195 Pt, 196 Pt, and 198 Pt), of which, 195 Pt is the most abundant stable isotope with a natural occurrence of 33.78%. The average atomic mass of platinum is 195.08 da.

2.3: Atomic Structure and Symbolism
Because the sum of the numbers of protons and neutrons equals the mass number, 127, the number of neutrons is 74 (127 − 53 = 74). Since the iodine is added as a 1− anion, the number of electrons is 54 [53 – (1–) = 54]. Exercise 2.3.1. An ion of platinum has a mass number of 195 and contains 74 electrons.
