Q

List two ways of testing weather something is a metal

A

See if it’s a solid at room temperature, see weather it’s appearance is dull or shiny, see if it conducts electricity, see if it is malleable, see if it reacts to heating

A

It is when atoms of the element are put together in different ways creating different forms of the element

24
Q

Two allotropes of carbon are..

A

Diamond and graphite

25
Q

Two allotropes of tin are…

A

White tin and grey tin

26
Q

What is there difference between the two allotropes of carbon (diamond and graphite)

A

Diamond is a hard transparent precious mineral whereas graphite is a slippery grey solid which conducts electricity. Is diamond each carbon atom bonds with 4 other carbon atoms whereas in graphite each carbon atom bonds with 3 other atoms.

27
Q
