- atoms
- all subst. made of atoms
- all elements only made from 1 atom (compounds 1+)
- periodic table is a way of organising all elements
- all elements only made from 1 atom (compounds 1+)
- all subst. made of atoms
- chemical equations
- no new atoms ever created or destroyed in reaction
- solids, liquids, gases and aqueous solutions
- symbol equations can be balanced
- solids, liquids, gases and aqueous solutions
- no new atoms ever created or destroyed in reaction
- seperating mixtures
- mixture is made of 2 substances not chemically bonded
- this means can be separated through physical means
- filtration - separates solids from solvent
- crystallisation separates soluble solid from solvent
- distillation - separates a solvent from soluble solids
- this means can be separated through physical means
- mixture is made of 2 substances not chemically bonded
- fractional distillation & paper chrom.
- FD separates miscible liquids with a fractioning column
- PC separates mixtures of substances dissolved in a solvent as they move up the chrom. paper
- history of the atom
- ions & isotopes
- atoms that gain electrons are negative ions
- isotopes are atoms of the same element with different numbers of neutrons
- electronic structure
- the electrons in an atom are in shells
- inner shell can hold 2
- outer shell can hold up to 8
- number in outer shell determines the reactivity
- the electrons in an atom are in shells
- atomic structure
- protons
- relative charge +1 relative mass 1
- neutrons
- relative charge 0 relative mass 1
- electrons
- relative charge -1 relative mass 0
- protons
- atoms
