Value Based Question
The chemistry teacher, while teaching her students, explained to them the differences
between 'metals' and 'non-metals'. She told them that both of them react with thesame gas-oxygen-but their resulting oxides are 'opposite' in nature.
She then went on to say that, in a somewhat similar way, we could use our stay in the
school either-
(i) to gain knowledge, learn good manners and develop, and tone up, different skills,
or
(ii) to indulge in idle gossip and other frivolous and irrelevant activities.
1.State two of the 'values' that the teacher conveyed to her students.
2.Give one example each of the reaction of a (i) metal, (ii) non-metal, with oxygen to
explain the opposite nature of the oxides formed in the two cases.
3.Let the students form two teams: M (Metals) and N (Non-metals); let the two teams
form 'pairs' to explain the differences between their properties.

Answer 1

2) When a metal reacts with oxygen it forms metal oxide

Na+O2=NaO

When a non-metal reacts with oxygen it forms non-metal oxide
