How long is the half life of platinum?
Naturally occurring platinum ( 78 Pt) consists of five stable isotopes ( 192 Pt, 194 Pt, 195 Pt, 196 Pt, 198 Pt) and one very long-lived ( half-life 6.50×10 11 years) radioisotope ( 190 Pt). There are also 34 known synthetic radioisotopes, the longest-lived of which is 193 Pt with a half-life of 50 years.
How many electrons are in a neutral platinum atom?
The number of electrons in an electrically-neutral atom is the same as the number of protons in the nucleus. Therefore, the number of electrons in neutral atom of Platinum is 78. Each electron is influenced by the electric fields produced by the positive nuclear charge and the other (Z – 1) negative electrons in the atom.
