Best Answers

Sodium belongs to Group I in the Modern Periodic Table, which consists of Alkali Metals. All the elements of this group, except Hydrogen, are extremely reactive metals, the reactivity increasing as we go down the group. read more

Sodium has larger atomic size because of less force of attraction between the valence electron and the nucleus, hence it is soft. You can also find that Potassium is more softer than Sodium, Rubidium being more softer than Potassium, and this goes on. read more

Some metals react to produce an acidic solution, some produce a basic solution, and others do nothing at all. It depends not only on what the metal is but also on what oxidation state the metal starts in. So, elemental sodium reacts with water to form a basic solution, but the +1 sodium cation in sodium chloride does not react with water at all. read more
