Question
When an inert atmosphere is needed for a metallurgical process, nitrogen is frequently used. However, in the reduction of $\mathrm{TiCl}_4$ by magnesium, helium is used. Explain why nitrogen is not suitable for this process.

Dinitrogen and argon are used for inert gas environments, for example in the laboratory to handle air-sensitive compounds. Argon is also routinely used in the car manufacturing industry as a protective blanket gas during arc-welding of metals. (a) Why is argon suitable as a protective gas? (b) Draw a Lewis structure for $\mathrm{N}_{2}$. What does the result tell you about the properties of the $\mathrm{N}_{2}$ molecule? (c) Construct an MO diagram for $\mathrm{N}_{2}$, and rationalize why $\mathrm{N}_{2}$ has a strong bond. (d) Why is $\mathrm{N}_{2}$ suitable for inert gas environments?

(d) $\Lambda \mathrm{r}$ is used in metallurgical processes.
Compounds sensitive to oxygen are often manipulated in glove boxes that contain a pure nitrogen or pure argon atmosphere. A balloon filled with carbon monoxide was placed in a glove box. After 24 h, the volume of the balloon was unchanged. Did the glove box contain $\mathrm{N}_{2}$ or $\mathrm{Ar}$ ?
