Answer:

1)Silver is the best conductor of electricity because it contains a higher number of movable atoms (free electrons). ... Copper is less conductive than silver but is cheaper and commonly used as an effective conductor in household appliances.

4)Metals usually have high melting point and boiling point. For example, iron, cobalt and nickel have high melting and boiling point. Tungsten has thehighest melting point. There are some exceptions - gallium and caesium have very low melting points.
