Solution

(a) Metal oxides;
They are usually solid at room temperature.
They are basic in nature
If they dissolve they form alkaline solutions.

Non metal oxide;
Usually gaseous at room temperature.
Are acidic in nature.
Dissolve in water to form acidic solutions.

Ex.
Metallic oxides are basic . react with acid to form salt . react with water to form base
CaO + $H_{2} O$ ------> $C a (O H)_{2}$

non metallic oxides are acidic. reacts with wter to form acids
$N_{2} O_{5}$ + $H_{2} O$ ----->2 $H N O_{3}$

b)Non-Metals C and S will form acidic oxide i.e. $S O_{2}$ and $C O_{2}$
Metals Na and K will form basic oxide i.e. $N a_{2} O$ and $K_{2} O$
Hydrogen will form neutral oxide i.e. $H_{2} O$ - Water
