Answer 6

Alkali
Metals
Form ionic compounds

Question 7

What are the group 7 elements properties (also known a halogens)

Answer 7

React with alkali metals

Form ionic compounds- Halide ions have a single negative charge

Question 8

List properties of an ionic compound

Answer 8

Giant ion structure

Ions held together by strong electrostatic attraction between oppositely charged ions- act in all direction in lattice

Question 9

List properties of covalent bonds

Answer 9

Strong bonds
Done consist of simple molecules such as cl2 and h2o however some have a giant covalent structure- macromolecules) e.g. Silicon dioxide and diamond
