The atomic number of an element tells you the amount of of electrons. In oxygen, symbol 'O', there are 8 electrons since the atomic number is 8.

For example, the atomic number of Hydrogen is 1, so there is 1 electron in a Hydrogen atom.

How many valence electrons are in CaO?

Calcium oxide (CaO) consists of calcium (Ca) and oxygen (O). Calcium, a group 2 element, has 2 valence electrons, while oxygen, a group 16 element, has 6 valence electrons. Therefore, in total, CaO has 2 (from Ca) + 6 (from O) = 8 valence electrons.
