- Elements of Life
- amount of substance
- relative atomic mass, Ar
- balanced equations
- relative molecular mass, Mr
- amount in moles n = m/Mr
- avogadro's constant = 6.02 x 10^23
- percentage yield = experimental yield/ theoretical yield x 100
- bonding
- metallic
- ionic
- covalent
- giant covalent network
- molecular covalent
- structure and properties
- ionisation energy:- decreases down a group- generally increases across a period
- the periodic table
- s-block: groups 1 and 2- reactivity increases down each group
- group 2 reactivity
- s-block: groups 1 and 2- reactivity increases down each group
- acids and bases
- concentration = moles/ volume
- oxonium ion: H3O+
- light and electrons
- speed of light = wavelength x frequency
- emission and absorption spectra
- energy of a photon = Planck's constant x frequency
- atomic structure: - protons and neutrons in the nucleus- electron cloud surrounds
- nuclear fusion
- shells, subshells and orbitals
- mass spectrometry (elements)
- mass spectrometry for compounds
- amount of substance
