Question

which of the following element is least metallic in nature ​

Answer 1

On moving down the group from Carbon to Tin the metallic character increases. This is due to the fact that the increase in atomic radius decreases attraction between the positive nucleus and the negative electrons, causing the electrons to be held more loosely.

Answer 2

Question - which of the following element is least metallic in nature a) iron b) lead c) copper d) hydrogen

The least metallic element is c) copper.

• Elements in metal reactivity series are arranged based on their ability to donate electrons. The reactivity of elements decreases when the reader goes down the table.
• Among the given options, copper is placed below others in the metal reactivity series. Hence, it is the least metallic.
• The metal reactivity series predicts the ability of elements to react with water and acid.
