It has no hardness.
Radon is a gas, no hardness.
One can obtain nitrogen gas at home by purchasing a nitrogen gas cylinder from a supplier or using a nitrogen gas generator to produce nitrogen gas from the air.
The product of nitrogen gas and oxygen gas is nitrogen dioxide (NO2) gas.
The hardness of krypton is not typically measured because it is a colorless, odorless, and tasteless gas at room temperature. Hardness is a property that typically applies to solid materials.
the nitrogen gas is used for nitrogen fixation
You can separate nitrogen gas from liquid nitrogen by allowing the liquid nitrogen to evaporate at room temperature or by heating it to increase the rate of evaporation. The nitrogen gas will separate from the liquid nitrogen as it evaporates, leaving behind the liquid nitrogen.
when the liquid nitrogen is boiled then it will turn into nitrogen gas.
Nitrogen gas is diatomic, meaning it consists of two nitrogen atoms bonded together (N2).
Argon is a noble gas and does not have a measurable hardness on the Mohs scale, as it is a gas at room temperature and pressure.
N2
No. Nitrogen is a gas.
Yes. Nitrogen gas has the formula N2. A molecule of nitrogen gas consists of two atoms of nitrogen covalently bonded.
