Answer 1

The charge and valance electrons of calcium and oxygen in a compound they form are 2 , 2, 6,2,+2,-2 respectively.

A calcium atom has 2 valence electrons. It needs to transfer 2 electrons to oxygen to have a full outer shell. An oxygen atom has 6 valence electrons It needs to accept 2 electrons from calcium to have a full outer shell. After the transfer of electrons, calcium becomes an ion with a +2 charge and oxygen becomes an ion with a -2 charge.

A valence electron is an electron in the outer shell associated with an atom, which can participate in the formation of a chemical bond if the outer shell isn't closed. In an unmarried covalent bond, both atoms within the bond contribute one valence electron that allows you to form a shared pair.

For impartial atoms, the range of valence electrons is identical to the atom's foremost organization number. the principle group-wide variety for an element can be located from its column on the periodic desk. for example, carbon is in institution four and has 4 valence electrons. Oxygen is in institution 6 and has 6 valence electrons.
