Activity 3.7 NCERT Class 10 Science, Chapter 3 Metals and Non-metals
Brief procedure:
Activity 3.7 asks us to compare the properties of metals discussed in earlier activities with some common non-metals.
Answer:
In activities from 3.1 to 3.6, we studied various properties of metals. They are:
1. Lusture 2. Hardness 3.Malleability 4. Ductility 5. Electric conductivity 6. Heat conductivity.
Metals generally carry all these properties except a few like mercury which is soft (liquid), Sodium and lithium which are not hard. Most non-metals have contrasting features with few exceptions like coal and graphite and diamond which are hard. Below table summarises the properties of some common non-metals.
Next: Reaction of metal oxides with water, Activity 3.8.

Nice explaining
Iodine has lustrous surface
This is the only website with good content of activities from ncert .
So I request the creators to please explain this particular activity in brief.
It is quite important for children
Iodine is lustrous and
Graphite conducts electricity
Iodine is lustrous
