1
Q
What is thermal stability?
A
A measure of the extent to which a compound decomposes when heated
2
Q
What is the trend in ionic radius down any group?
A
It increases
3
Q
Why?
A
Because more shells are being added
4
Q
What is the trend in thermal stability of group 1 nitrates?
A
Increases down the group
5
Q
Are group 2 nitrates more or less thermally stable than group 1 nitrates?
A
Less
6
Q
Why?
A
Due to their greater charge
7
