Newland's Law of Octaves
The first try at arranging in rows of & based on atomic mass, broke down at transition metals and was dismissed due to no gaps/mixed non/metals and diff properties
1 of 8
Mendeleev
Russian scientist who left gaps which were filled to form the modern table
2 of 8
Electronic structure
How the electrons in an atom are arranged
3 of 8
Group Number
Eg Group 1/7 correspond to number of outer shell electrons
4 of 8
Shielding
When alot of inner electrons get in the way of nuclear charge
5 of 8
Alkali metals
GROUP 1 Lithium, Sodium and Potassium- silvery soft solids kept in oil that burn skin. Down+ more reactive higher m/b points, 1 outer electron, ionic w non metals, move in water and squeaky pop
6 of 8
Halogens
GROUP 7 Fluorine etc Non metals w coloured vapous, down= less reactive and low m/b points. Ionic bonds w metals
7 of 8
Transition metals
Big clump of 'typical metals' in table, often more than 1 ion which normally form diff colours like weathered copper and gemstones
