Answer 1

1.Sodium and potassium

2.mercury

3.Ductility is the ability of a material to be drawn or plastically deformed without fracture. Silver is a soft metal with high thermal and electrical conductivity. It is malleable andductile similar to gold. However, silver content in ores mines in India is about 1% obtained as a by-product in mining of gold and lead. Thus, silver is highly expensive to be drawn into wires for the industries

4.Gold and iron.
