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.
Chlorine is a non metal element. There are 17 electrons in a single atom.
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
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.
