Answer 2

Answer:

All the given options are not compound.

Explanation:

• In general there are two types of substances they are: one is element and other is compound.
• Element is a pure substance. That means it consists of only one atom. They cannot be decomposed into other atoms.
• Elements are classified as metals, non- metals and semi metals. Compound atoms are the combination of two atoms.
• They can be split into different atoms by some external field.
• For example: water $\mathrm{H}_{2} \mathrm{O}$, Sodium chloride (salt) $\mathrm{NaCl}_{2}$, and calcium carbonate $\mathrm{CaCO}_{3}$ are the compounds where they can be split into two different atoms.
