WebApr 9, 2024 · The periodic trend of atomic radius across a period – As we move from left to right in a period, atomic radius gradually decreases. Reason – As we move left to right in a period the atomic number of the elements increases so nuclear charge increases while the number of shells in elements remains the same. Example –. WebJul 12, 2024 · The other hydroxides in the group are even more soluble. Solubility of the hydroxides increases down Group 1. In Group 2, the most soluble is barium hydroxide—it is only possible to make a solution of concentration around 3.9 g per 100 g of water at the same temperature of 20°C. It is difficult to explain the trends in solubility.
