Question

Give the names of the elements present in:

glucose

Answer 1

Glucose $\left({\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6\right)$ is a compound.

Compound: A compound is a pure substance in which different elements combine chemically in a fixed composition to give a compound.

• They can be broken down into elements that make up the compound by using chemical or electrochemical methods.
• Example: Water $\left({\mathrm{H}}_2\mathrm{O}\right)$, Common salt i.e. Sodium chloride $\left(\mathrm{NaCl}\right)$

To find out the elements present in glucose:

Step-1: Write the chemical formula of the compound

• Glucose is a compound with the chemical formula ${\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6$

Step-2: Identify the elements present in the compound from their chemical symbols

S.No	Symbol of the element	Name of the element
1	$\mathrm{C}$	Carbon
2	$\mathrm{H}$	Hydrogen
3	$\mathrm{O}$	Oxygen

Element: An element is a pure substance that cannot be split into simpler substances.

• Example: Hydrogen $\left({\mathrm{H}}_2\right)$, Copper $\left(\mathrm{Cu}\right)$ etc.
