Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The number of electrons in the outermost energy level when most elements are chemically stable is ____
A
8
B
6
C
3
D
1
Explanation: 

Detailed explanation-1: -Most of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule.

Detailed explanation-2: -The tendency of atoms to have eight electrons in the outer shell is known as the “octet rule” or “Rule of eight”.

Detailed explanation-3: -The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react and form more stable compounds.

Detailed explanation-4: -Atoms with 8 electrons in their valence shell have completely filled last orbitals and are therefore the most stable, as their electronic configuration is similar to that of the closest noble gas.
