New cards
the first ionisation energy
The amount of energy required to remove 1 electron from every ion in mole of atomic gas, to produce a mole of uni positive gaseous ions
2
New cards
the second ionisation energy
The amount of energy required to remove 1 electron from every ion in one mole of uni positive gaseous ions to produce a mole of dispositive gaseous ions
3
New cards
the third ionisation energy
the amount of energy required to remove 1 electron from every ion in one mole of dispositive ions to produce a mole of tripositive gaseous ions
4
New cards
factors affecting ionisation energy
electron sheilding, atomic radius, nuclear charge
5
New cards
how does electron sheilding affect ionisation energy
The more electrons shielding the outer electron shell from the nucleus lesser is the energy required to expel an electron from the atom
6
New cards
how does nuclear charge affect ionisation energy
The more protons in the nucleus means the nucleus has a greater positive charge. therefore
