As the atoms get larger down the group, the bonding pair is further from the nuclei and the strength of the bond should, in theory, decrease, as indicated in the figure below.

It highlights their tendency to exist in nature combined with other substances, such as salts found in the ocean.

The sodium or potassium ions are spectator ions and therefore irrelevant to the reaction, which proceeds as follows:

Visualization methods can be either non-destructive (compound is unchanged after the process) or destructive (compound is converted into something new after the process. Viewing a TLC plate under ultraviolet light is non-destructive, while using a chemical stain is destructive.
