First ionisation energy is the energy needed to remove an electron from an atom in one mole of gaseous atoms
1 of 8
What is second ionisation energy/successive?
Second ionisation energy is the energy needed to remove an electron from an ion in one mole of gasous ions with a single positive charge.
2 of 8
What factors effect ionisation energy?
The distance of the nucleus and the outer shell electrons, the sheiding(in terms of electrons repelling), the amount of protons(nucleur charge)
3 of 8
how does nucleus charge affect ionisation energy?
The more protons in the nucleus, the more positively charged the nucleus is, increasing the attraction.
4 of 8
Why does successive ionisation energy increase within each shell?
Because electrons are being remove, therefore creating a more positive species increasing the attraction, as there is now less replusion amongst the remaining electrons.

How many lone pairs does water have and what bond angle does it have?
2 lone pairs at an angle of 104.5
