The African plate is splitting apart to form two separate plates.

The Eurasian plate is converging with the African plate.

The African plate is colliding with the Arabian plate.

a. hope i'm right

explanation:

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
