Question

Find the odd one out:
a) $NaCl$, $MgC{l}_2$, $H_2$ (based on type of bonding)
b) $Li,Na,F$ (based on metals and non-metals)

Answer 1

(a) $\underset{}{NaCl,Mg{Cl}_2}\underset{}{H_2}\left(b\right)\underset{}{Li,Na}\underset{}{F}$

$\underset{}{Ionic}$, $\underset{}{Covalent}$ Metals Non-metal

$\left({Na}^{+}{Cl}^{-}\right),\left({Mg}^{2+}{2Cl}^{-}\right)$ $H-H$
