GCSE CHEMISTRY - The Reactivity Series - Metal Displacement Reactions …

The Reactivity Series Metal Displacement Reactions. A metal will displace (take the place of) a less reactive metal in a metal salt solution. This is similar to the non-metal displacement reactions seen on page 23 of the periodic table. For example, iron + copper(II) sulfate iron sulfate + copper.

Reactivity Series of Metals - Get the Chart, Significance and …

2018/4/6· This article is on reactivity series of metals. Metals are usually inclined to form ions through electron loss, reacting with oxygen in the air to form oxides over various timescales (iron rusts over years, while potassium burns in seconds). Examples: 4 Na + O 2 → 2 Na 2 O (sodium oxide) 2 Ca + O 2 → 2 CaO (calcium oxide) 4 Al + 3 O 2
