Question

A molecule can be made of which of the following? many elements a single element a single atom

Answer 1

Answer:

A single element or many elements  

Step-by-step explanation:

A molecule consists of two or more atoms of the same or different elements that are bound together.

Examples of molecules are O₂, H₂O, CH₂O, and C₂H₃OCl.

C is wrong, because a molecule must contain at least two atoms.

Answer 2

Answer: Option (a) is the correct answer.

Explanation:

When two or more atoms are chemically combined together then the product formed is known as a molecule.

These atoms can be bonded through either covalent or ionic bonds.

For example, a water molecule consists of two hydrogen atoms combined with an oxygen atom. Chemical formula of water is $H_{2}O$.

Thus, we can conclude that an element can be made of many elements.
