Remember the octet rule, it must have 8 electrons in its outer shell. If it is bonded to one atom, then it has six unshared electrons in its outer orbital.

7.... it has a -1 charge as an ion, so 8 (the stable number of valence electrons) minus 1 is 7

its an halogen...it has 7 electronvalens and it means it needs 1 electron to make it stables..
thats why it has -1 value for the ion..
