Question

What's properties and uses group 1 and group 2 element

Answer 1

Answer:

Low density - can float on water. Low melting points in comparison with other metals. They react violently (in some cases) with water to form alkaline solutions - hence the name, alkali metals. Reactivity increases as you descend the group.

Answer 2

Answer:

Group 1 elements:

Alkali elements or the group 1 elements

lithium,sodium, potassium,rubidium,caesium are group 1 elements

Properties :

1. they have low melting and boiling points
2. they can easily donate their valence electrons to form strong ionic bonds
3. they are soft and can be cut through knife
4. they have low densities
5. lubricant grease is produced through lithium
6. sodium is used as luster in metals
7. k helpful for growth of plants
8. rubidium used for making optical glasses

Group 2 elements:

they are less reactive than the alkali metals

they are good conductors of electricity

can easily loose electrons

Properties:

1. they are used in important materials from cement
2. ca is key component for all living beings
3. mg is used as antacids etc.
