All of 11 electrons in sodium are in different electron orbitals: 2 electrons are in 1s orbital, 2 in 2s, 6 in 2p and 1 in the 3s orbital. (This last one is the so-called valence electron)
One electron in 3s orbital of sodium

Xenon is found in group 18. It has an electronic configuration of 2, 8, 18, 18, 8 and has eight valence electrons (or eight electrons in the outer most orbital).
No. Valence electrons are the electrons in the outer most orbit (or energy level) and not in outer most orbital.

Be (beryllium) has four electrons total: the first orbital, the 1s orbital, has two, which leaves two electrons in the outer shell.
One electron in 3s orbital of sodium
It needs to lose one electron so that it can have 8 electrons in its outer orbital

Valence electrons are electrons found in the outer orbital (shell of an atom) They are the electrons used for bonding

No. Valence electrons are the electrons in the outer most orbit (or energy level) and not in outer most orbital.

Sodium is in the third group in the periodic table. It meens that sodium has three shell. First shell - 2 electrons, second shell - 8 electrons, third shell (outer energy level) - 1 electron.
The elements which falls under the group 16 has 4 electrons in its outer p orbital...
These electrons are called "outershell electrons" or "valence electrons."
The most stable outer orbital arrangement of electrons after a chemical reaction is 8 electrons. This is referred to as the octet rule in representative elements.
