Question

where on the periodic table do we get negative ions?

Answer 1

atoms near a complete octet will have a tendency to *gain* electrons rather than lose them... this means they will have a surplus of negative charge and thus be negative ions

Answer 2

so look to the right of the periodic table, left of the noble gases -- these elements, the halogens, etc., give rise to neutral atoms which tend to form negative ions

Answer 3

so things like \(F,Cl,N,O,etc.\)

Answer 4

examples include, Cl-, F-, I-, O--
