Calcium (Ca) normally has 20 protons and 20 electrons, which makes it a neutral atom because the number of protons (positive charges) and electrons (negative charges) are equal, balancing each other out.

However, in this case, the mass number is given as 42. The mass number is the sum of protons and neutrons. Since Calcium always has 20 protons, this means there are 22 neutrons (42-20=22).

The number of electrons is still 20. Therefore, the atom is still neutral because the number of protons (20) equals the number of electrons (20).

So, this atom would be classified as an isotope of Calcium (because it has more neutrons than typical Calcium) and would have an electrical charge equal to 0 (because the number of protons equals the number of electrons).
