​

Answer 1

Explanation:

1 true

2 false

3 true

4 true

Answer 2

1) Mercury is a metal with very low melting point. TRUE

2) Bromine is a non metal with high melting point. FALSE

3) Mercury and Bromine are liquid metals. TRUE

4) Mercury is a liquid metal and bromine is a liquid non metal. TRUE

Explanation:

1) Because of the behavior of valance electrons and therefore mercury has a low melting point as well as poor electrical and thermal conductor.

2) Bromine is a non metal with low melting point,

3) Mercury and Bromines are liquid metals at room temperature. Mercury is the only metal that is liquid at room temperature.

4) Mercury is a liquid metal and Bromine is a liquid non metal.
