Periodicity
As you move from left to right:
As you move from top to bottom:
Period 2 and 3 Oxides, Chlorides, and Hydrides
- Ionization energy increases
- Electronegativity increases
- Atomic radius decreases
- Electron affinity increases
- Density decreases
- Oxidizing power increases
- Reducing power decreases
As you move from top to bottom:
- Ionization energy decreases
- Electronegativity decreases
- Atomic radius increases
- Electron affinity decreases
- Density increases
- Oxidizing power decreases
- Reducing power increases
- Metals generally have high melting and boiling points and non-metals have lower melting points. Moving down the group in metals decreases melting and boiling points. Moving down the group in non-metals increases melting and boiling points.
- Metals have high conductivity while non-metals do not, and metalloids have moderate conductivity
- Oxidation number is usually the same as the charge of the ion of the element, with some exceptions with hydrogen and oxygen.
- Fluorine has the highest oxidizing power because it is the most electronegative. The more electronegative elements have higher oxidizing power.
- Cesium has the highest reducing power because it is the least electronegative. The less electronegative elements have higher reducing power.
Period 2 and 3 Oxides, Chlorides, and Hydrides
- Period 2 oxides and chlorides go from ionic to covalent from left to right
- Period 2 hydrides go from ionic, covalent, to polar covalent, but there is no clear trend of acidity
- Period 3 oxides and chlorides go from ionic to covalent from left to right
- Period 3 hydrides go from basic to acidic from left to right, and go from ionic, covalent, to polar covalent
