The periodic table is a tabular array of the chemical elements organised by atomic number, from the element with the lowest atomic number, hydrogen, to the element with the highest atomic number, oganesson. The atomic number of an element is the number of protons in the nucleus of an atom of that element. Hydrogen has 1 proton, and oganesson has 118. In this lesson we look at the structure of the periodic table and where the different types of elements occur on the periodic table.

Balancing chemical equation
If there are no inequalities, the chemical equation is said to be balanced. In this lesson we look at the balancing of chemical equations and why it is important. We also learnt how to balance the equations.
