Far too many - it needs to gain 16 to get to Krypton which is the next noble gas (energetically impossible) - It is far easier for it to lose 2 (which it does) to get to the Argon structure
Calcium is more likely to lose electrons because it has two electrons in its outermost shell, making it easier for calcium to achieve a stable electron configuration by losing these two electrons to become a positively charged ion.
Calcium usually loses 2 electrons, giving a cation of Ca2+
Calcium is a lender of electrons because it tends to lose two electrons to achieve a stable electron configuration. It forms ionic bonds by giving away these electrons to elements that need to gain electrons to achieve stability.
A chlorine atom would gain one electron to become an ion because it tends to achieve a stable electron configuration by having a full outer shell of electrons.
Sulfur gains 2 electrons to become stable.
Metals will LOSE electrons to become stable.

The metals aluminum, calcium, and potassium will give up electrons to be stable. Chlorine is a nonmetal and it will gain an electron in an ionic bond in order to be stable.
to become stable
A calcium atom typically loses two electrons to form a calcium ion with a 2+ charge. The loss of these electrons allows the calcium ion to achieve a stable electron configuration similar to that of a noble gas.
bcc it's the same
lose 2
Calcium has two electrons in its outermost shell (the 4s subshell). To achieve a full outer shell, which would correspond to the stable electron configuration of neon, calcium must lose these two electrons. Therefore, calcium loses two electrons to gain a full outer shell.
Calcium has two valence electrons in its outer shell. To achieve a stable octet configuration of eight valence electrons, it needs to lose these two electrons rather than gain any. Therefore, calcium does not need to gain any electrons; instead, it will typically lose two to achieve stability.
