no, it just has to be in group 5 on the Periodic Table
A halogen is located in group 17 of the periodic table, so the electron configuration for the valance electron would be ns2np5 (n=energy level). So all halogens have 7 valance electrons.
There are 17 electrons i a neutral atom of chlorine.
There are 17 electrons present in a chlorine atom.
Halogens are group 17 elements. They have 7 valence electrons.
Chlorine, atomic number 17, has 17 protons. So an uncharged atom has 17 electrons.But when Chlorine takes on 1 electron, which often happens in ionic bonds, it has 18 electrons, which fills the outer shell of electrons.
By looking at the group number you can tell how many valance electrons there are ex: Group 1= 1 valance electrons Group 2-12= 2 valance electrons Group 13= 3 valance electrons Group 14= 4 valance electrons Group 15= 5 valance electrons Group 16= 6 valance electrons Group 17= 7 valance electrons Group 18= 8 valance electrons
Chlorine is a non metal element. There are 17 electrons in a single atom.
17 electrons. The number of protons and electrons is always the same.
Chlorine is a metal element. There are 17 electrons in a single atom.
Element 17's valence electron configuration is 3s23p5.
A chlorine atom typically has 17 electrons in its electron cloud.
The chlorine atom has 17 protons and electrons.
