What is the trend down the group and across a period for Groups 1 and 2?
Elements become more metallic down a group and elements become less metallic across a period
1 of 13
What are the properties of s-block elements?
Soft, weak metals with low melting points. Too reactive with water and oxygen
2 of 13
What is the definition of the first ionisation enthalpy?
The energy needed to remove an electron from every atom in one mole of isolated gaseous atoms of the element - a mole of gaseous ions with one positive charge are formed
3 of 13
What is the general trend in ionisation enthalpy across period 3?
The first ionisation enthalpy increases
4 of 13
What are at the troughs and peaks of an ionisation enthalpy graph?
Group 1 elements are at the troughs and Group 0 elements are at the peaks
5 of 13
What is formed when a Group 2 element reacts with oxygen?
A metal oxide
6 of 13
What is formed when a Group 2 element reacts with water?
A metal hydroxide and hydrogen
7 of 13
What is formed when a Group 2 carbonate is decomposed?
A metal oxide and carbon dioxide
8 of 13
What is the trend in thermal stability down Group 2?
The thermal stability increases

What is the trend in reactivity with water down Group 2?
Reactivity increases
10 of 13
What is the trend in pH down Group 2?
pH increases
11 of 13
What is the trend in the solubility of hydroxides down Group 2?
