Answer:

Calcium can lose 2 electrons to make the ion calcium, following this equation:

Ca → Ca2⁺ + 2e⁻

Explanation:

Calcium is the third element of group TWO in the periodic table. As it belongs to group two, it means that can lose 2 electrons to get the noble gas configuration that corresponds. It is a metal from the group of alkali earth metals.

Since its tendency is to lose electrons, it is said to form charged ions (+)

Saturation.

Explanation:

Hello,

In this case, the statement is accounting for the saturation vapor pressure as it is the pressure of a vapor which is in equilibrium with its liquid, in other words it is the maximum exerted pressure possible by the vapor at a given temperature or just the maximum amount of the vapor, so there is neither no more vapor that could condense nor more liquid that could boil.

Best regards.
