Answer:
Sodium (Na) is an alkali metal. It is so soft that it can be cut with a knife.
Sodium is so reactive that it vigorously catches fire when kept open in air and hence, we keep it immersed in kerosene oil.
Sodium oxide is the basic oxide formed as sodium metal reacts with oxygen of air at room temperature.
