An octet is 8 electrons- but even 2 electrons are okay for achieving stability.

A beryllium atom has 2 shells, with 2 electrons in each shell. Since it is a metal, it will lose electrons instead of gaining them, forming a positively charged ion.

This means that it will lose both the electrons in its outermost shell, leaving it with a single shell containing 2 electrons.

So, basically beryllium loses 2 to electrons to form a stable duet with a charge of 2+!

Hope this helped you (:

How does the octet rule help you determine the oxidation number of an element?

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons. By following this rule, you can determine the oxidation number of an element based on how many electrons it gains or loses in order to reach a full octet. The oxidation number corresponds to the charge an atom would have if the compound were ionic.

eight. it is important to obtain octet so that elements become stable.
