Question

fill in the missing words
o₂ is the chemical formula for elemental ____,
n₂ is the chemical formula for elemental ____,
h₂ is the chemical formula for elemental ____.

Explanation:

Step1: Analyze \( O_2 \)

Oxygen is a diatomic element in its elemental form, so \( O_2 \) is the formula for elemental oxygen.

Step2: Analyze \( N_2 \)

Nitrogen is also diatomic in elemental form, so \( N_2 \) is the formula for elemental nitrogen.

Step3: Analyze \( H_2 \)

Hydrogen is diatomic as an element, so \( H_2 \) is the formula for elemental hydrogen.

Answer:

\( O_2 \) is the chemical formula for elemental \(\boldsymbol{\text{oxygen}}\), \( N_2 \) is the chemical formula for elemental \(\boldsymbol{\text{nitrogen}}\), \( H_2 \) is the chemical formula for elemental \(\boldsymbol{\text{hydrogen}}\).
