Successive Ionisation Energy Flashcards
1
Q
Definition of Successive Ionisation Energy
A
It’s the energy needed to remove 1 electron from each ion in 1 mole of gaseous +1 ion from 2 moles of gaseous +2 ions
2
Q
The shell structure and ionisation energies
A
- Within each shell the ionisation energy increases due to electrons being removed from the outer shell forming a increasing positive ion
3
Q
Why are there big jumps in ionisation energy?
A
This is due to a shell breaking and the outer most electrons are closer to the nucleus.
4
Q
How do you know which group an element is?
A
Looking at the ionisation energy as there is a big jump, the group is when the jump happens
for example: 12, 44, 55, 698, 700, …
This shows that there was a jump between 3 and 4 therefore the group of the element is 3.
