The atomic mass of the element is 45.

An atom's mass is its atomic mass. Although the kilogram is the international system of unit measure of mass, the unified atomic mass unit, or dalton, is a common way to express atomic mass.

The charge number of an atomic nucleus is the chemical element's atomic number, also known as the nuclear charge number.

An element has 20 protons, 20 electrons, and 25 neutrons.

The atomic number is the number of protons, hence the atomic number is 20.

The atomic weight or mass is the sum of the number of protons and neutrons.

Therefore,

20 + 25 = 45

The atomic weight is 45.
