Using the information on the figure above, report the atomic number and atomic mass of fluorine.

The atomic number and atomic mass of fluorine is 9 and 19 respectively.

Explanation:

Atomic number is defined as the number of protons or electrons that are present in a neutral atom.

Atomic number = number of protons = number of electrons

Atomic mass is defined as the sum of number of protons and neutrons that are present in an atom.

Atomic mass = Number of protons + Number of neutrons

We are given:

Fluorine is the 9th element of the periodic table.

We know that:

Atomic number of fluorine = 9

Atomic mass of fluorine = 19

Hence, the atomic number and atomic mass of fluorine is 9 and 19 respectively.
