Atomic Orbitals and Ionisation Flashcards
Use your knowledge of Atomic orbitals to determine electron configuration.
1
Q
Define Ionisation Energy
A
The energy required to remove one mole of electrons from one mole of gaseous atoms to form one mole of gaseous cations.
2
Q
What is the electron configuration of Fluorine?
A
1s^2 2s^2 2p^5
3
Q
What is the electron configuration of Chromium
A
1s^2 2s^2 2p^6 3s^2 3p^6 4s^1 3d^5
4
Q
Why Group 1 metals have low first ionisation energy
A
Because the s^1 electron is far away from the nucleus, causing the distance effect.
5
Q
Why does Sodium have higher second and third ionisation levels?
A
Distance effect.
