ICl2- is 10, if you are in Ap Chem on WebAssign then this is probably what you are looking for....
-I already got it right on WebAssign:)
its electrons that are found in the shells around an atom.
Sulfur (S) would be the central atom, and it will have 6 Cl bonded to it by single bonds. Each Cl will have 3 lone pairs of electrons around them. S will have 12 electrons but it can have an expanded octet, and doesn't have to have 8 electrons.
B in BH3 has an incomplete octet because it only has 6 valence electrons. 3 of its own and 1 from each hydrogen The central atom does not have 8 valence electron in the molecule.
By gaining 3 electrons
One.
An octet of electrons is when the outermost electron shell of an atom contains eight electrons.
8

when the outer most shell of an atom was said to have 8 electrons then it was said to possess an octet
By gaining 3 electrons
Bromine is a non metal element. There are 35 electrons in a single atom.
It depends which 'other atom' it is
One.
gain 2 electrons
it forms covalent bonds by sharing electrons
