Periodic Classification of Elements - Characteristics of Groups: Valence Electrons and ValencyThe groups in the Periodic Table are arranged vertically. There are 18 groups in the Periodic Table. All the elements in one group have the ...

A flame test can work to identify the metal ion (a charged particle) in a solution. The chemical compound (X Chloride) is heated and a coloured flame is made.

It can be deduced which metal ion is in the solution according to the colour released

when the solution is heated in a blue flame.

The colours are made when the valence electrons gain energy from the flame and move up from 'ground state' to the next energy level. They are said to be in an 'excited state' at this point. Shortly after, they will move back down to their original position ("ground state" again) and as they do this they release energy. This energy emission is seen as coloured light.

Flame Test - Javalab* This simulation take the spectral data from NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY. When heat is applied to the atoms, some electrons can have high energy levels and fall to the lower levels. Some electrons emit as much energy...
