A chlorine atom has 7 valence electrons.
Ionic because in a dot diagram Magnesium has 2 valence electrons and chlorine has 7 valence electrons. With 2 chlorine atoms there are two spots for electrons to jump over because each chlorine atom has room for one more electron and so both of magnesium's valence electrons would jump over to either chlorine. I hope this helped!
There are 7 electrons on the valence shell. Chlorine requires one electron to make it complete and the ion would therefore be Cl- (one minus charge)
halogens
Fluorine's properties would more closely resemble those of chlorine than those of oxygen. This is because both F and Cl are in the same group (group 7, the halogens) and each has 7 valence electrons. Oxygen is in group 6, and has only 6 valence electrons.

Both iodine and chlorine are halogens (group 17) and have 7 valence electrons.

The are none.

Hydrogen has one valence electron. To form a compound, it must follow the octet rule, which states that the total outermost orbital (valence) contains eight electrons. The Chlorine atom contains seven valence electrons. H(1) + Cl(7) = 8 (follows the octet rule)
halogens
Helium has 2 valence electrons, and it's the only noble gas that doesn't have 8 valence electrons.

Cl:Cl Since each of the chlorines in the molecule is sharing one electron with the other they both get an octect. They only share one of their electrons with the other. So 7+1=8The chlorine atoms could share a pair of valence electrons.
They are the electrons in the outermost shell, and are the ones involved in most chemical reactions.
