Chemistry Flashcards
Diffusion
The movement of particles from an area of high concentration to an area of lower concentration
Element
Substances that are only made up from one type of atom
Compound
substance made up from two or more types of atom chemically bonded
Mixture
Substance made up from two or more types of atom, or compound that are not chemically bonded
Solute
A substance dissolved into water or another solvent
Solvent
A liquid substance that other substance can dissolve in to
Solution
The combination of a solute and a solvent
Solids
High density, low movement, hard, keep there shape
Liquid
Dense, can flow, no fix shape, same volume
Gas
Low density, free to move, high energy, no fixed shape or volume
electron
Negatively charged, mass 1/1870
Neutrons
No charge, mass 1
Proton
positively charge, mass 1
Filtration
A liquid can past though the filtration paper but not the solid
Distillation
When a solutes is dissolve in to a solvents. then heated up. then the solvent evaporates leaving only the solutes
Chromatography
A piece of paper with a coloured dot is dipped into water as the water travels up the paper the colour move with the water
Chemical change
Change in colour, gas, heat and light and being released
Antoine Lavoisier
found the element in 1789
John Dalton
He stated that atoms could be chemically join in 1803
J.J. Thopson
The reasons atoms are made up of two part in 1890
Niels Bohr
Made planetary model for the arrangement of proton, neutron and electrons
Erwin Schrodinger
the cat
Solid to gas
sublimation
solid to liquid
melting
