3.1.2 - Group 2

Question 1

What are Group 2 elements usually referred to as?

Answer 1

Alkaline Earth Metals

Question 2

Are Group 2 metals reactive or not?

Answer 2

These metals are very reactive and so they are found on earth as compounds e.g. metal carbonates/nitrates/sulfates

Question 3

What happens to group 2 elements when they react?

Answer 3

Lose the 2 outer electrons in the s sub shell to form 2+ ions and become stable

Question 4

What kind of reactions do Group 2 elements take part in?

Answer 4

Redox reactions as Group 2 metals are reducing agents

Question 5

What happens to reactivity as you go down group 2?

Answer 5

Increases

Question 6

Why will Group 2 elements get more reactive as we go down the group?

Answer 6

its easier for them to lose the two outer most electrons because:
Atomic Radius Increases
Nuclear Attraction Decreases
Electron Shielding Increases

Question 7

What are some uses of Group 2 elements?

Answer 7

• Medicine
• Agriculture

Question 8

Do group 2 elements get oxidised or reduced?

Answer 8

Oxidised

Question 9

What type of bonds are group 2 elements likely to form?

Answer 9

Ionic bonds

Question 10

How do group 2 elements get extracted?

Answer 10

Electrolysis, Phytomining, Bioleaching

Question 11

How are group 2 elements found?

Answer 11

Found in ores as metal carbonates, sulfates & nitrates.

Question 12

Why do group 2 elements have high melting & boiling points?

Answer 12

Strong metallic bonds

Question 13

What do the metallic bonds in group 2 elements form (structure-wise)?

Answer 13

giant metallic lattice
