Question

oxygen and nitrogen are both gases at room temperature. explain why oxygen has a greater force of attraction between its particles than nitrogen.

Explanation:

Oxygen has a higher - molar mass than nitrogen. London - dispersion forces, which are the main intermolecular forces in non - polar molecules like $O_2$ and $N_2$, increase with the molar mass. Larger molar mass means more electrons, leading to greater temporary dipoles and stronger London - dispersion forces.

Answer:

Oxygen has a greater molar mass than nitrogen. The greater number of electrons in oxygen molecules leads to stronger London - dispersion forces between its particles compared to nitrogen.
