Question

Sodium is a very reactive metal.Is the statement true or false?

Answer 1

Answer:

Explanation:

As a part of the alkali metal group in the periodic table, sodium is highly reactive and is never found pure in nature. It tarnishes easily and has a low melting point and density.sodium is so reactive because they lose their valence electron very easily.

Answer 2

The given statement, Sodium is a very reactive metal, is TRUE.

Explanation:

Sodium is a highly reactive metal, so it is stored under kerosene. When a small piece of sodium is dropped in water, it starts floating with a hissing sound, and soon, the metal piece catches fire.

Sodium reacts vigorously with water and air and they catch fire automatically.

Reaction with water:

In this reaction, Sodium reacts with cold water, and sodium hydroxide is formed with the release of hydrogen gas a tremendous amount of heat is released.

$\bf 2Na \ (Sodium) \ + \ 2H_2O \ (Water) \rightarrow 2NaOH \ (Sodium \ hydroxide) \ + \ H_2 \ (Hydrogen)$

Reaction with oxygen:

Sodium reacts with oxygen to form Sodium oxide.

$\bf 4Na \ (Sodium) \ + \ O_2 \ (Water) \rightarrow 2Na_2O \ (Sodium \ oxide)$

Some more information:

• The atomic number of Sodium is 11.
• Its electronic configuration is  2, 8, 1.
• Sodium is a part of the 1st group of elements.
• The first group of elements are highly reactive.
