Unit 1: Periodicity Flashcards
1
Q
Trend of covalent radius going across period
A
Decrease - increasing/stronger nuclear charge
2
Q
Trend of covalent radius going down group
A
Increase - more electron energy shells, outer electron shell shielded from pull of nucleus
3
Q
Ionic radius trend going across period
A
Decrease - negative ions larger than parent atom
4
Q
Ionic radius trend going down group
A
Increase
5
Q
Ionisation energy trend across period
A
Increase - stronger nuclear charge
6
Q
Ionisation energy trend down group
A
Decrease
7
Q
Electronegativity trend across period
A
Increase - stronger nuclear charge (more attraction between bonds)
8
Q
