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).
An atom of phosphorus (P) has five outer orbital electrons in its third energy level, as it has 15 electrons in total with electronic configuration 2-8-5.
Chlorine has 7 electrons in its outer shell.
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)

Be (beryllium) has four electrons total: the first orbital, the 1s orbital, has two, which leaves two electrons in the outer shell.
Five. Fluorine and chlorine are in the 2p and 3p shells, respectively. Because each p orbital contains a maximum of six electrons, and fluroine and chlorine both have one less, they each have five.
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).
Valence electrons are electrons found in the outer orbital (shell of an atom) They are the electrons used for bonding
A chloride anion contains eight outer shell electrons, one more than the seven outer shell electrons found in a chlorine atom.
An atom of phosphorus (P) has five outer orbital electrons in its third energy level, as it has 15 electrons in total with electronic configuration 2-8-5.
Chlorine has 7 electrons in its outer shell.
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)

When a typical atom's outer orbital is filled, it will have 8 electrons, except for helium which will have 2 electrons. This is because the outer orbital, known as the valence shell, can hold a maximum of 8 electrons.
Two electrons in the outer shell of radium.
The elements which falls under the group 16 has 4 electrons in its outer p orbital...
