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 [tex]H_{2}O[/tex].
Thus, we can conclude that an element can be made of many elements.
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.
