Answer 1

sodium and potassium are highly reactive and catches fire easily b) siver is the good conductor of heat c) is too long Sry d) high melting point because they have strong force of attraction e) it is A lead which conducts electricity and is used in various purpose

Answer 2

A) Na and K are stored in kerosene because when they come in contact with air they vigorously react with oxygen and catches fire.

B) Mercury(hg)
