Expert Answer

Step 1

An atom consists of three sub particles: protons, electrons and neutrons.

The atomic number of a neutral atom represents the number of protons and electrons.

The mass number of a neutral atom represents the sum of protons and neutrons.

Step 2

In fluorine : 19F9

Atomic number = 9

Mass...

Fluorine (F)
Atomic mass
no. of protons = no. of electrons = 9
=
Mass number no. of protons no. of neutrons
No. of neutrons = mass number - no. of protons
No. of neutrons = 19 - 10 9
