* They are both gases at room temperature and pressure. This is because they are diatomic molecules (N2 and O2) with weak intermolecular forces.
* They are both essential for life on Earth. Nitrogen is a key component of proteins and DNA, while oxygen is used by most organisms for respiration.
* They are both found in the atmosphere. Nitrogen makes up about 78% of the Earth's atmosphere, while oxygen makes up about 21%.
* They are both colorless, odorless, and tasteless. This is true in their gaseous state.
* They are both nonmetals. This means they lack the properties of metals, like conductivity and malleability.
