To solve this question, we need to know the atomic number of Ca, which is 20.

Atomic number = protons number = electrons number if the atom is neutral

Number of neutrons we calculate using the following formula:

A = p + n; where A = mass number; p = number of protons; n = number of neutrons.

For 40Ca:

Atomic number: 20

Number of protons: 20

Number of neutrons:

A = p + n

40 = 2 + n

n = 20

Number of electrons: 20

Mass number: 40
