1AtomsElectrons=-1
Neutrons=0
Protons=+1
2IsotopesDifferent forms of the same elements which have the same number of protons but not neutrons
3ElementsConsist of atoms with the same atomic number
4Compounds-Atoms combine with other atoms to form compounds
-Substances formed from two or more elements
5FILTRATIONSeparates insoluble solids from liquids
EVAPORATION and CRYSTALLISATION separate soluble solutions from solids and to separate rock salt
6History of the atomJohn Dalton= solid spheres
JJ Thompson=wernot solid spheres contained electrons
'Plum Pudding Model'
-Ball of positive charge with electrons in it
7Plum Pudding Model was wrongErnst Rutherford proved the model was wrong
He fired POSITIVELY CHARGED ALPHA PARTICLES at a thin sheet of gold.
Ernst Rutherford discovered protons
8Neils BohrNeils Bohr created a nuclear model stating electrons were contained in shells and orbit the nucleus
9James ChadwickJames Chadwick discovered protons
10Dmitri MendeleevMendeleev took 50 elements and ordered them in atomic mass in the periodic table
11Metals and non-metalsMetals=Metallic Bonding
Non-Metals= More Brittle
