Verified step by step guidance

Understand the diatomic nature of nitrogen: Nitrogen exists as a diatomic molecule (N₂) in its elemental form. The two nitrogen atoms are connected by a triple bond, which is one of the strongest types of chemical bonds.

Explore the reactivity with metals: When nitrogen gas is heated with active metals, it can form metal nitrides. This is because the strong triple bond in N₂ can be broken under high temperatures, allowing nitrogen to react with metals.

Consider the stability of nitrogen gas: Nitrogen gas (N₂) is relatively stable due to the strong triple bond between the nitrogen atoms. This bond requires a significant amount of energy to break, making N₂ inert under normal conditions.

Examine the use of nitrogen gas as a protective atmosphere: Due to its stability and inertness, nitrogen gas is often used as a protective atmosphere in various industrial processes to prevent oxidation and other reactions that could occur in the presence of oxygen.

Conclude that all statements are true: Each statement about nitrogen is accurate based on its chemical properties and uses, confirming that the correct answer is 'all of the above.'
