Assuming you mean "halogen": 1, usually. Things like "perchlorate ion" are something else again...
All have six valence electrons.
how many valence electrons does family 1 have
4 electrons
Halogen family members, or elements in group 17, have 7 valence electrons.
it is in the oxygen family and has 6 valence electrons it requires 2 electrons
Since fluorine and chlorine are in family 7A, they each have 7 valence electrons. The number of the family corresponds to the number of valence electrons.
There are 8 valence electrons in the noble gases, the family of elements furthest to the right on the periodic table.
As,Arsenic belongs to nitrogen family in periodic table so it has 5 valence electrons.
7
There's 3.
8 valence electrons are there in in neon's family .They are stable in nature.
The neon family, also known as Group 18 on the periodic table, contains elements with 8 valence electrons. This includes elements such as helium, neon, argon, krypton, xenon, and radon. Valence electrons are the electrons in the outermost energy level of an atom.
