Detailed explanation-1: -Electrons in the outermost energy level of an atom are called valence electrons.

Detailed explanation-2: -This outermost shell is known as the valence shell, and the electrons found in it are called valence electrons. In general, atoms are most stable, least reactive, when their outermost electron shell is full.

Detailed explanation-3: -Valence electrons are the electrons that are found in the outermost energy level of an atom.

Detailed explanation-4: -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. Some atoms can be stable with an octet even though their valence shell is the 3n shell, which can hold up to 18 electrons.

Detailed explanation-5: -The valence electrons are the electrons in the outermost shell or last energy level of an atom. Valence electrons are electrons in the highest principal energy level. They are electrons that sit in the outermost shell of an atom.
