Resource summary

F321: Bonding and Structure
1 Ionisation Energies
1.1 Factors affecting ionisation energies
1.1.1 Atomic radius: the greater the radius, the smaller the nuclear attraction by the outer electrons
1.1.2 The greater the nuclear charge, the greater the attraction on the outer electrons,
1.1.3 Electron shielding: inner electrons repel outer electrons, this is called shielding, the more inner shells there are, the greater the shielding and the smallerthe nuclear attraction experienced by the outer electrons.
1.2 Successive ionisation energies
1.2.1 successive ionisation energies are the measure of energy required to remove each electron in turn
1.2.2 e.g second ionisation energy is how easily a 1+ ion can turn into a 2+ ion by loosing 11electron
1.2.3 each successive ionisation energy is higher than the one before as each electron is removed there is less repulsion between the electrons and each shell with de drawn in closer to the neucleus As the distance from the electron to the nucleus is less the higher the nuclear attraction therefore a higher ionisation needed to loose another electron
2 Shells and orbitals
2.1 electrons in each shell
2.1.1 n=1 shell=1 electrons =2
2.1.2 n=2 shell=2 electrons =8
2.1.3 n=3 shell=3 electrons =18
2.1.4 n=4shell =4 electrons =32
2.1.5 each shell holds up to 2n^2
2.1.6 principal quantum number = n
2.2 Atomic Orbitals
2.2.1 S-orbitals sphere shape In every shell Holds up to 2 electrons
2.2.2 P-orbitals 3D dumbbell shape from the second shell up they contain 3 p orbitals at right angles to each other each p orbital can hold 2 electrons, total p electrons =6
2.2.3 D&F-orbitals from shell 3 they contain 5 d orbitals and total of 10d electrons from shell 4 they contain 7 f orbitals and total of 14f electrons
3 Sub-shells and energy levels
