Verified step by step guidance1
Step 1: Understand the question is asking for the correct chemical formula of nitrogen monoxide, which is a compound made of nitrogen and oxygen atoms.
Step 2: Recall that 'monoxide' means there is one oxygen atom in the molecule, so the formula should have exactly one oxygen atom.
Step 3: Examine each option to see which has one oxygen atom: \(N_2O\) has one oxygen, \(NO_2\) has two oxygens, \(NO\) has one oxygen, and \(N_2O_3\) has three oxygens.
Step 4: Consider the naming conventions: 'nitrogen monoxide' specifically refers to the compound with one nitrogen and one oxygen atom, which corresponds to the formula \(NO\).
Step 5: Conclude that the correct chemical formula for nitrogen monoxide is \(NO\) because it matches both the name and the number of atoms indicated by 'monoxide'.
