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.
The atomic number of platinum is 78, which means it has 78 protons in its nucleus. The atomic mass of platinum is approximately 195.08 g/mol, which is an average of the different isotopes of platinum found in nature.
They do not combine with or interact with most other elements or compounds. ... radioactive. No radioactive isotope of platinum has any commercial application.
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.
78. This is the atomic number of platinum, and any platinum isotope will have this number of electrons per atom.
Isotopes. They differ in the number of neutrons in the nucleus.
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..
Platinum has 6 naturally occurring isotopes, all of which have 78 protons. The number of neutrons can vary, but the most common isotopes have between 116 and 118 neutrons. The full list of isotopes is:190Pt (78 protons and 112 neutrons)192Pt (78 protons and 114 neutrons)194Pt (78 protons and 116 neutrons) about 1/3 of all platinum195Pt (78 protons and 117 neutrons) about 1/3 of all platinum196Pt (78 protons and 118 neutrons) about 1/4 of all platinum198Pt (78 protons and 120 neutrons) about 1/14 of all platinum
Neon with an extra neutron would be considered an isotope of neon. Isotopes have the same number of protons but a different number of neutrons. Since it still has the same number of protons (and thus still the same atomic number), it remains an ion.
Isotopes differ by the number of protons.
Neon has the atomic number 10 which means it has 10 protons, it cannot have 12. Different isotopes of an element have the same number of protons but a different number of neutrons. There are three stable isotopes of neon.
To write an isotope you will write the mass number in the upper left-hand corner, then under it you will write the number of protons, then next to this you will write the symbol for the element.So...for the isotope of platinum that contains 118 neutrons:Protons (from the periodic table of elements) = 78Mass Number = neutrons (118) + protons (78) = 196Element symbol = PtAnd it will look something like this:196 Pt78
