Chemistry Unit 1: The Periodic Table

HideShow resource information
Period
A period is a horizantal row of elements in the Periodic Table. Elements shows trends in properties across a period.
1 of 7
Group
A group is a vertical column in the Periodic Table. Elements in a group have similar chemical properties and their atoms have the same number of outer-shell electrons.
2 of 7
Periodicity
Periodicity is a regular periodic variation of properties of elements with atomic number and position in the Periodic Table.
3 of 7
Thermal Decomposition
Thermal decomposition is the breaking up of a chemical substance with heat into at least two chemical substances.
4 of 7
Displacement Reaction
A displacement reaction is a reaction in which a more-reactive element displaces a less-reactive element from an aqeous soloution of the latter's ions.
5 of 7
Disproportionation
Disproportionation is the oxidation and reduction of the same element in a redox reaction.
6 of 7
Precipitation Reaction
A precipitation reaction is the formation of a solid from a solution during a chemical reaction. Precipitates are often formed when two aqueous solutions are mixed together.
