(ii) a cation
(iii) a pair of isotopes
(iv) an atom of noble gas.
(v) write the electronic configuration of Element C.

Most suitable answer will be handsomely rewarded.
Please I don't understand this so please not only answer but also explain.

Answer 1

Answer:

1.anion equals to d,e as it has 17 electrons and ions will gain electron to have a stable electronic configuration.

2.cation = a

4.noble gas= cas it has 18 pair of electrons it will have stable electronic configuration thus it is a noble gas
