group 2

Question 1

properties of group 2 metals

Answer 1

-shiny
-metallic bonding
-giant metallic lattice
-high mp and bp
-conduct electricity
-reactive
-when they react they are oxidised
-strong reducing agents
-+2 ions

Question 2

how is atomic radius effected as you go down the group

Answer 2

-it increases as there are more shells

Question 3

how does shielding affect atomic radius in group 2

Answer 3

-shielding increases as there are more shells between the outer electron/shell and the nucleus so attraction is reduced and electrons are lost more easily

Question 4

what does a group 2 metal produce when reacting with oxygen

Answer 4

metal oxide

Question 5

what does a group 2 metal produce when reacting with water

Answer 5

metal hydroxide and hydrogen

Question 6

what does a group 2 metal produce when reacting with hydrochloric acid

Answer 6

metal chloride

Question 7

what does a metal carbonate produce when heated

Answer 7

metal oxide and carbon dioxide

Question 8

what does a metal carbonate produce when added with hydrochloric acid

Answer 8

metal chloride + water + carbon dioxide

Question 9

what is thermal decomposition

Answer 9

an endothermic reaction when you add heat to a compound and the compound breaks apart
