The graph shows a sketch of the first ionisation energies of six successive elements in the Periodic Table.
The letters are not the symbols of the elements.
Explain what is meant by the term first ionisation energy.
Suggest why the first ionisation energy of B is much less than that of A.
P–T are successive elements in Period 3 of the Periodic Table.
The letters are not the symbols of the elements.
On the axes, sketch a graph to show the trend in the atomic radius of the elements P–T.
