Explanation:

First part can be found on pretty much any periodic table.

Number of protons in atomic number, it's not an isotope so the number of protons and neutrons are equal, the number of electrons is also the same in a single atom.

The number of electrons is 19. The first level can hold a maximum of two, and the rest can hold up to eight. The first three get completely filled up and then there is a remainder of one for the fourth level.

The rest are just general facts.

Hope this helps!
