What are the isotope of platinum which contain 118 neutrons?

Answer 1

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) = 78

Mass Number = neutrons (118) + protons (78) = 196

Element symbol = Pt

And it will look something like this:

196 Pt

78

Answer 2

Platinum has several isotopes with 118 neutrons, including Pt-194, Pt-195, Pt-196, and Pt-197. These isotopes have different numbers of protons, which determine their atomic number and chemical properties.

Answer 3

On average, most gold atoms have about 118 neutrons.

Some gold atoms have more and some have less, these are called isotopes of gold.

Answer 4

The isotope of platinum that contains 118 neutrons is Pt-196 (platinum-196)

Answer 5

196

Pt

78
