Answer:

It will lose 2 electrons

Explanation:

Here we have a calcium atom, which has 20 electrons.

Those 20 electrons are in 4 shells. (2-8-8-2)

Saying there are 2 electrons in the valence shell (Shell N), to get to an octet with an ionic bond (with a group 16 element), those 2 electrons will have to go.
