The valence electrons of representative elements are

Question

a
located in the outermost occupied major energy level.
b
in s orbitals only.
c
located closest to the nucleus.
d
located in d orbitals.
e
located in the innermost occupied shell.

Answer 1

The correct answer is:

a) located in the outermost occupied major energy level.

Valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding. They can be found in s and p orbitals, depending on the element, but they are specifically characterized by their position in the outermost energy level (or shell) of the atom.
