What is the formula of the 1st ionisation energy
X(g) → X+(g) + e-
2
New cards
what is the formula for the 2nd ionisation energy?
X+(g) → X2+(g) + e-
3
New cards
what is the formula for the 3rd ionisation energy?
X2+(g) → X3+(g) + e-
4
New cards
what happens to the ionisation energy and nuclear attraction when atomic radius decreases?
ionisation energy increases and nuclear attraction increases
5
New cards
how to tell which group an element is based on its ionisation energy?
any large jumps in ionisation energy mean that it has moved to a new shell, closer to the nucleus
6
New cards
when counting ionisation energy numbers, which atom do you start from?
the electrons on the outermost shell, working inwards
