The outer shell is the valence electrons and they are very loosely bound to the nucleus - less force by the nucleus on the valence electrons, so valence shell's electrons are exchanged first in any reaction.
in the third shell, an electron has more energy and is further from the nucleus
It represents the family the element is in.

A Bohr-Rutherford diagram for a sodium atom, which has 11 protons and 11 electrons, features a nucleus at the center containing 11 protons and typically 12 neutrons. Surrounding the nucleus are two electron shells: the first shell holds 2 electrons, and the second shell holds 8 electrons, with the remaining 1 electron occupying the third shell. The diagram visually represents the arrangement of electrons in concentric circles around the nucleus, illustrating the atom's structure and electron configuration.
The outer shell of an atom is the valence shell, which contains the valence electrons.
An oxygen atom has six (6) electrons in its outer shell.

A neutral neon atom has 8 electrons in its outer shell. Neon has a total of 10 electrons, with 2 in the inner shell and 8 in the outer shell.

the valence shell
The valence shell is the outermost shell...and an atom can only have one outer shell.
The outer-most shell of an atom is called the valence shell. It is involved in forming chemical bonds with other atoms.
Electrons are found in an atom's outer shell. The outer shell, also known as the valence shell, is where the electrons involved in chemical reactions and bonding are located. The number of electrons in the outer shell determines the atom's chemical properties.
When an atom forms an ion, the outer shell of the ion will have gained or lost electrons to achieve a full valence shell. For cations (positive ions), the outer shell will have fewer electrons than the neutral atom. For anions (negative ions), the outer shell will have more electrons than the neutral atom.
