Question

How is molecule whose formula is NO different from the molecule whose formula is N2O?

Answer 1

The correct answer is A. N2O has 2 nitrogen atoms, whereas NO has only one.

For a chemical compound, the chemical formula depicts the proportions in which the atoms are present in that particular compound. So the chemical formulas indicate the type of elements and the number of atoms of each element present in the compound. The atoms of each element are represented by their chemical symbol and the number of times the element is present s represented as a subscript on that element.

In $N_{2}O$, the subscript on N is 2 so there would 2 N atoms and 1 O atom in each molecule of $N_{2}O$.

NO has one nitrogen atom and one Oxygen atom.

Answer 2

The correct answer is option A, that is, N₂O has 2 nitrogen atoms, whereas NO has only one.

A molecule with the formula NO comprises one oxygen atom and one nitrogen atom, while the molecule with the formula N₂O comprises two nitrogen atoms and one oxygen atom.
