Question

Would you expect each of the following atoms to gain or lose electrons when forming ions? Whation is the most likely in each case?
a. Ra
b. In
C. P
d. Te
e. Br
f. Rb

Short answer

The gain or loss of electrons when ion formation can be found.

Step-by-step solution

Gain or loss of electrons when forming ions in Ra

The Ra will comes under group 2. Thus, it is an alkaline earth metal with electron valence of 2. This is like to lose ionic bond when have high electronegative element in group 16 (6). It will lose electrons for formation of${\mathrm{Ra}}^{2+}.$

Gain or loss of electrons when forming ions in In

There are three valence electrons, it will loss an ionic bond to high electronegative element in group 15 (5). These will lose electrons for the formation of${\mathrm{In}}^{+}.$

Gain or loss of electrons when forming ions in P

There are 5 valence electrons and it will take three more to form ionic bond from less electronegative element belongs to group 13 (3). So, P will gain electrons for the ion formation${\mathrm{P}}^{3-}.$

Gain or loss of electrons when forming ions in Te

There are 6 valence electrons and it will take two more to form ionic bond from less electronegative element belongs to group 2. Te will gain electrons for Ion formation${\mathrm{Te}}^{2-}.$

Gain or loss of electrons when forming ions in Br

There are 7 valence electrons and it will take one more to form ionic bond from less electronegative element belongs to group 1. This will gain electrons for Ion formation

${\mathrm{Br}}^{-}.$

Gain or loss of electrons when forming ions in Rb

There are only one valence electrons and it will take two more to form ionic bond from less electronegative element belongs to group 17 (7). This will lose electron for the Ion formation${\mathrm{Rb}}^{+}.$
