Platinum has six naturally occurring isotopes. They range from 190 to 196 in Atomic Mass. There are 31 synthetic isotopes in platinum that range from 166 to 202 in atomic mass.

Because chlorine has two natural isotopes (and isotopes have different number of neutrons) the total number of neutrons is 30 and 32.
An ISOTOPE> Remember the definition for isotopes. Different isotopes of an element have a different number of neutrons. NB Ions are produced when an atom has a different number of electrons compared to the number of protons.
Isotopes must have the same atomic number, which is the number of protons. The atomic mass, which is the total number of protons and neutrons, varies for the different isotopes. so it should have different mass numbers..
Isotopes. They differ in the number of neutrons in the nucleus.
An estimated 117 neutrons. This can vary as platinum has different isotopes of different mass thus resulting in varying number of neutrons.
Isotopes differ by the number of protons.
Platinum atom has 78 protons and electrons; the number of neutrons is variable and depends on the atomic mass of the isotope (atomic mass of the isotope - atomic number = number of neutrons). The stable isotopes have 114, 116, 117, 118, or 120 neutrons.
Platinum is a metal element. Atomic mass of it is 195.08.
The atomic number is the same for the isotopes of a chemical element.
Isotopes of the same element have the same number of protons (atomic number) but differ in number of neutrons (hence atomic masses).
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
