Step 1

Isotopes are the atoms of an element with same number of protons and electrons but different number of neutrons.

The isotope can be expressed in form of X-A where X is the chemical symbol of element and A is the mass number of the isotope.

Step 2

The mass number is defined as the sum of number of protons and neutrons in a nucleus.

And

Atomic number defines the number of protons in a nucleus. Each element has a fixed atomic number.

Step 3

Part A:

Now we are given an Argon isotope with 18 neutrons.

Chemical symbol of Argon is Ar

Atomic number of Argon = 18

Therefore, Number of Protons in ...

Mass number of Argon Number of protons + number of neutrons
= 1818 36
