Explanation / Answer

Ans 69 :

To determine whether the element will gain or lose electron to form an ion (in a faster way) , just look at its position in modern periodic table.

If the element is closer to the left end of the table , it tends to lose the electron (s) to form a cation , and if it is closer to the right end of the table , it will accept the electron (s) to form anion.

So basically you have to look for the minimum number of electrons that can be added or removed from the valence shell of the atom , so that it can have a stable completely filled octet.

So here :

a) Ra : Ra2+

b) In : In3+

c) P : P3-

d) Te : Te2-

e) Br : Br1-

f) Rb : Rb1+
