An element ‘A’ form two oxides AO and AO2. The
oxide AO is neutral whereas the oxide AO2 is acidic
in nature. Would you call element ‘A’ a metal or a
non-metal?
The element is carbon which is a non- metal. CO is
neutral and CO2 is acidic in nature.

A student, took four metals P, Q, R and S and carried out different experiments to study the properties of metals. Some of the observations were:
- All metals could not be cut with knife except metal R.
- Metal P combined with oxygen to form an oxide
- M2O3 which reacted with both acids and bases.
- Reaction with water:
P- Did not react either with cold or hot water but reacted with steam.
Q-Reacted with hot water and the metal started floating
R- Reacted violently with cold water.
S - Did not react with water at all
1. Out of the given metals, the one which needs to be stored in kerosene is

2. Metal which forms amphoteric oxides is
(a) P (b) Q (c) R (d) S.
3. The increasing order of the reactivity of the four metals is
(a) P<Q<R <S (b) S<R<Q<P (c) S<P<Q<R (d) P<R<Q<S.

Aluminium is highly reactive metal but still used for making cooking utensils. Aren't humans afraid that Al might react with food and cause probs......... So why?
It forms an oxide layer on its surface which makes it passive.
