metals and non metals

Question 1

what is a non metal’s key characteristic

Answer 1

non metals always accept electrons to gain a full outer shell

they can form negative ions or can share electrons to do this

Question 1

what is a metal atom’s key characterist

Answer 1

metals always donate electrons to gain an empty outer shell to form positive ions

Question 2

How are metals good conductors of electricity and thermal energy

Answer 2

They are electrical conductors because their delocalised electrons carry electrical charge through the metal.

They are good conductors of thermal energy because their delocalised electrons transfer energy.

Question 3

What are Properties of metals (7 answers)

Answer 3

They have high melting points and boiling points because the metallic bonding in the giant structure of a metal is very strong

They are malleable which means they can be bent and shaped easily

They are strong

Shiny

Good conductors of electricity

Good conductors of heat

High density

Question 4

What are Properties of nonmetals (6 answers)

Answer 4

Dull

Low melting points

Poor conductors of electricity

Poor conductors of heat

low density

Brittle
