Question

Identify the odd one out.

The correct answer is

Steel

Oxygen, hydrogen and nitrogen are pure chemical elements, each listed in the periodic table, and all three are gases at room temperature.

Steel is not an element. It is an alloy, a mixture made mainly of iron with a small amount of carbon (and sometimes other metals).

So steel differs from the other three in its basic chemical nature.

Hence, Steel.
