Question

Number of electrons in 120g of Ca2+? ​

Answer 1

Answer:

you ask about the electrons (and maybe protons) and neutrons in a single Ca2+ ion, the protons and electrons are easy. The atomic number of calcium is 20, meaning that it has 20 protons in the nucleus and since it has a net charge of +2, there are 18 electrons left in the electron cloud surrounding the nucleus

now you can find in 120 g
