The Periodic Table: chemical periodicity — practice question
The sketch graph plots the first ionisation energies for six consecutive elements in the Periodic Table. The letters do not represent the elements' symbols.
(a(i))[3]
Explain what the term first ionisation energy means.
(a(ii))[3]
Suggest why the first ionisation energy of B is much lower than that of A.
(b)[3]
On the axes, sketch a graph to show the pattern in the atomic radius of the elements P-T. Explain your answer.
