Explanation / Answer
If it ends on the "p" orbital then the you get the periodic group summing electrons in "s" and "p" orbitals, then:
S = 2, P= 5 ...........Periodic group = 2+5 = 7A or 17
It is a non-metal, so it attract electrons. The ion has negative charge. (-1)
If it ends on the "s" orbital then you get the periodic group directly from the electrons in "s" orbtial, then:
S = 1................Periodic group: 1A or 1
It is a alkaline metal, so the ion has positive charge (+1)
