Where is reactivity on the periodic table

A reactivity series of metals could include any elements. For example:. A good way to remember the order of a reactivity series of metals is to use the first letter of each one to make up a silly sentence.

Observations of the way that these elements react with water, acids and steam enable us to put them into this series. The tables show how the elements react with water and dilute acids:. Note that aluminium can be difficult to place in the correct position in the reactivity series during these experiments.

In the periodic table:. You can imagine a zig-zag line, starting at B-Al-Si, separating metals from non-metals. The periodic table shows that metals are found in groups 1, 2 and 3. These metals will have 1, 2 or 3 electrons in the outer shell. The outer shell of a metal is, therefore, less than half full of electrons.

How an element or compound will easily gain or lose electrons when interacting with other elements. Reactivity can also be a measure of how violent a reaction is giving our heat or light.

The nucleus is the term given to the centre of the atom comprising of the proton and neutron. Table of Contents. Atomic Structure. Element Names and Symbols. Elements in Everyday Life. Groups and Periods.
