Period 1 of 6 A regular periodic variation of properties of elements with atomic number and position in the Periodic Table. Periodicity 2 of 6 The breaking up of a chemical substance with heat into at least two chemical substances. Thermal decomposition 3 of 6 A reaction in which a more-reactive element displaces a less-reactive element from an aqueous solution of the latter's ions. Displacement reaction 4 of 6 The oxidation and reduction of the same element in a redox reaction. Disproportionation 5 of 6 The formation of a solid from a solution during a chemical reaction. Precipitates are often formed when two aqueous solutions are mixed together. Precipitation reaction 6 of 6
