Question

An atom of a certain element has 36 protons, 36 electrons and a mass number of 84.

At room temperature this element is a very stable gas. How many neutrons are in this atom?

Answer 1

There are 48 neutrons in the atom

Step-by-step explanation:

Here, we want to calculate the number of neutrons in the atom

Mathematically;

Number of protons + Number of neutrons = mass number

Number of neutrons = Mass number - Number of Protons

Number of neutrons = 84-36

Number of neutrons = 48
