How many electrons will each atom either gain or lose in order to satisfy the octet rule of Na?

Each sodium atom will lose one electron to achieve a complete octet in its outer shell, as the octet rule dictates atoms will gain or lose electrons to achieve a stable electron configuration with 8 electrons in the outer shell.


How many valence electrons will beryllium gain or lose to fill its outer shell?

Beryllium will lose 2 electrons to satisfy the octet rule (to fill its outer shell).


Does strontium transfer electrons or take in electrons or share them?

Strontium lose electrons.


Do you gain or loose electrons to satisfy outet aluminum?

Aluminum must lose 3 electrons to satisfy the octet rule. Once it does this, it becomes the Al+3 ion, and is isoelectronic with noble gas neon.

No, metals tend to lose electrons to achieve a full octet.


Does strontium Sr gain or lose electrons?

Strontium (Sr) typically loses two electrons to form a stable 2+ ion. It belongs to group 2 of the periodic table, which means it has 2 valence electrons that it tends to lose to achieve a full outer shell.


Does strontium lend or borrow electrons?

Strontium tends to lose electrons and form a 2+ cation because it is an alkaline earth metal with two valence electrons.


How many electrons must strontium lose to have a noble gas electron configuration?

It should lose two electrons
