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

Do metals usually gain or loose electrons to be stable?

Metals will LOSE electrons to become stable.


Is calcium more likely to gain or lose electrons?

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.


Can you consider aluminum chlorine calcium and potassium give up electrons to be 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.


Why do you think atoms lose electrons to or gain electrons from other atoms?

To form an ion what does a calcium atom gain or loose?

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.

How electrons will magnesium gain or lose to become stable?

lose 2


How many electrons are loss for calcium to gain a full outer shell?

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.


How many electrons does calcium need to get eight valence electrons?

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.


Loss or gain of electron for calcium?

Calcium usually loses 2 electrons, giving a cation of Ca2+
