What is the trend of ionisation energies down Group 2 elements?
AS we go down the group,Ionisation energy DECREASEs because the electrons are getting further and further away from the positive nucleus. This makes the electrons easy to remove so it would only take little energy

What is the trend in solubilities of hydroxides?
As we go down the group they become more soluble

When the group 2 metals react with water,what is the trend in reactivity?
The metals get more reactive as we go down the group

What is the test for sulfate ions in a solution?
First make the solution acidic by adding nitric or hydrochloric acid, then add barium chloride, if a sulfate is present a white ppt is formed
5 of 9
What is the solubility trend in sulfates?
The sulfates are more insoluble down the group
6 of 9
The hydroxide are all white solids?
True
7 of 9
what is the trend in atomic radius down group 2 elements?
The atoms get bigger (atomic radii increases) because each element has an extra filled main level of electrons compared to the one above it
