We just need to look at protons to determine which atom (element it is). Calcium has 20 protons. To include neutrons in the answer, we do one or the other:
Calcium-X (where X is the number of neutrons and protons)
Calcium-42
or
42
.....Ca
20
Element: Calcium (Ca)

`.`.Ca
20
Basically it's an isotope of Calcium, as it has 22 neutrons. The most abundant form has 20 neutrons, which has an atomic mass of 40.078.

Calcium has atomic mass 40 and proton number 20.
A mass of an atom is the sum of protons and neutrons
MAss = Protons + Neutrons
Normally for calcium the equation will be:
40 mass = 20 neutrons + 20 protons
But since this one hass 22 neutrons, it is an isotope of Calcium (i.e. it has a different number of neutrons)
42 - (mass)
Ca
20 (proton number)

Ca-42 (You have to add the number of neutrons and protons)
(Ca = Calcium)
