topic 2a - bonding and structure (8. metallic bonding)

Question 1

what is the structure of a metal

Answer 1

regular pattern, giant structures because they have a lot of atoms

Question 2

what is the bonding in metals

Answer 2

the electrons in the outer shells of the atoms are delocalised. they are free to move around the structure.l strong forces of electrostatic attraction between the positive metal ions and the negative metal ions known as metallic bonding hold the structure together.

Question 3

properties of metals

Answer 3

high melting and boiling points, high conductivity, malleable, layers are able to slide over each other

Question 4

what are alloys

Answer 4

alloys are pure metals mixed with other metals to make them harder. as pure metals are too soft. allys are more useful
