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
lose 2
bcc it's the same
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.
Calcium usually loses 2 electrons, giving a cation of Ca2+
to gain or lose electrons to become stable
None.Calcium loses 2 electrons to form an ion.
Oxygen has six valence electrons, which means that it needs to gain two to become stable. it takes much more energy for oxygen to lose its 6 valence electrons than it would be to gain 2. When atoms form compounds, they become stable.
