Question

Give reason:
Electronegative ions are formed when an atom has atomic number (Z) as 17

Answer 1

THE ATOM CHANGES INTO ELECTRONEGATIVE BCOZ LOSING 7 ELECTRON TO ATTAIN THE NOBLE GAS CONFIGURATION IS IMPOSSIBLE AS IT REQUIRES MORE ENERGY

SO INSTEAD OF LOSING 7 ELECTRON IT GAINS ONE MORE ELECTRON TO ATTAIN OCTET

SO THE ATOM WITJ ATOMIC NUMBER 17 CHANGES INTO ELECTRO NEGATIVE IONS

Answer 2

TO LOSE 7ELECTRONS IT WILL NEED MORE ENERGY SO IT GAIN 1 ELECTRON TO COMPLETE THE OCTATE.

SO THE ATOM WITH ATOMIC NUMBER 17 CHANGES INTO ELECTRO NEGATIVE IONS
