What are the Properties of an alkali liquid?

Answer 1

The alkali metals have the following properties in common:

• they have low melting and boiling points compared to most other metals.
• they are very soft and can be cut easily with a knife.
• they have low densities (lithium, sodium and potassium will float on water)

Answer 2

Chemical properties:

1. one valence electron

2. highly reactive

Physical properties:

3. low melting points (compared to other metals)

4. soft (can be cut with knife unlike other metals)

5. shiny surface

Answer 3

alikali metals- group seven

low melting point and boiling point- increases down the groups

dark colours- increases down the group

reactivity decreases down the group

react with metals to from ionic bonds or metal to form covalent bonds.

Answer 4

Looses electrons. Located : group 1 periods 1-7

EXAMPLE: lithium Li 3 L-1

Answer 5

Low melting and boiling point
