Decompression in divers or astronauts can cause the ‘bends’ – a potentially fatal condition when nitrogen bubbles form in the bloodstream. Characteristics: Nitrogen is a colorless, odorless, tasteless, diatomic and generally inert gas at standard temperature and pressure.
Similarly one may ask, what is the state of nitrogen at room temperature?
Uses: Nitrogen – N2 – at room temp and atmospheric pressure, nitrogen is a colorless, odorless, nontoxic, nonflammable gas. It constitutes 78% by volume of the atmosphere.

How do we use nitrogen?
Nitrogen is important to the chemical industry. It is used to make fertilisers, nitric acid, nylon, dyes and explosives. To make these products, nitrogen must first be reacted with hydrogen to produce ammonia. This is done by the Haber process.
What are the physical and chemical properties of nitrogen?
Characteristics. Nitrogen gas (chemical symbol N) is generally inert, nonmetallic, colorless, odorless and tasteless. Its atomic number is 7, and it has an atomic weight of 14.0067. Nitrogen has a density of 1.251 grams/liter at 0 C and a specific gravity of 0.96737, making it slightly lighter than air.
What are the characteristics of the nitrogen family?
The top two elements, nitrogen and phosphorus, are very definitely nonmetals, forming -3 charge anions. Nitrogen is a diatomic gas and phosphorus is a solid. The elements arsenic, antimony, and bismuth all have some characteristics of semimetals such as brittleness as a free element.

How cold is nitrogen?
(-346°F and -320.44°F). Below 63 K, nitrogen freezes and becomes a solid. Above 77.2 K, nitrogen boils and becomes a gas. Since it is obtained from the atmosphere, liquid nitrogen is inexpensive and is rarely refrigerated.
What color represents nitrogen?
Common colorsHydrogenwhiteCarbonblackNitrogenblueOxygenredFluorine, chlorinelight green
Is nitrogen gas is flammable?
Air is mostly nitrogen, which is not flammable. Nitrogen is also non-reactive in general, so it doesn’t support the combustion of other materials, either. After nitrogen, the most abundant gas in our air is oxygen.
Is nitrogen harmful for humans?
Because 78 percent of the air we breathe is nitrogen gas, many people assume that nitrogen is not harmful. However, nitrogen is safe to breathe only when mixed with the appropriate amount of oxygen. These two gases cannot be detected by the sense of smell.
Is nitrogen luster?
Nitrogen is a nonmetal. Like other elements in this group, it is a poor conductor of heat and electricity and lacks metallic luster in solid form. The name became nitrogen, which derives from the Greek word nitron, which means “native soda” and genes, which means “forming”.
Can nitrogen be harmful to humans?
The air we breathe is already 78% nitrogen. The problem is that nitrogen displaces oxygen. Normal air is 21% oxygen. Lower than 19% begins to have measurable effects and lower than 10% is considered critically dangerous.
Is nitrogen an atom?
Nitrogen. Nitrogen is a chemical element with symbol N and atomic number 7. At standard temperature and pressure, two atoms of the element bind to form dinitrogen, a colourless and odorless diatomic gas with the formula N2. Dinitrogen forms about 78% of Earth’s atmosphere, making it the most abundant uncombined element
How does nitrogen get its name?
Nitrogen was first isolated by Scottish chemist Daniel Rutherford in 1772. He called the gas “noxious air.” Nitrogen was named by French chemist Jean-Antoine Chaptal in 1790. He named it after the mineral niter when he found that niter contained the gas.
Is nitrogen poisonous?
While it should definitely be handled safely, liquid nitrogen is not poisonous. In fact, nitrogen is everywhere. The element nitrogen makes up 78% of the Earth’s atmosphere. That means the air you breathe is made up of mostly nitrogen gas, not the ever popular oxygen.

What is the function of the nitrogen cycle?
The conversion of nitrogen can be carried out through both biological and physical processes. Important processes in the nitrogen cycle include fixation, ammonification, nitrification, and denitrification. The majority of Earth’s atmosphere (78%) is nitrogen, making it the largest source of nitrogen.
Is nitrogen a metal or non metal?
The non-metals or non-metallic elements; hydrogen (H), carbon (C), nitrogen (N), oxygen (O), phosphorus (P), sulphur (sulfer) (S), selenium (Se), (Uuo may belong here) and the noble gases form a relatively small group with a step like pattern towards the left-hand side of the periodic table (hydrogen being the odd one
Is nitrogen a nonmetal?
The nonmetal elements occupy the upper right-hand corner of the periodic table. The nonmetal element group is a subset of these elements. The nonmetal element group consists of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur and selenium.
How is nitrogen bad for the environment?
Nitric oxide is not considered to be hazardous to health at typical ambient concentrations, but nitrogen dioxide can be. NOx gases react to form smog and acid rain as well as being central to the formation of fine particles (PM) and ground level ozone, both of which are associated with adverse health effects..
What are some interesting facts about nitrogen?
Nitrogen is a chemical element with the symbol N and atomic number of 7. Under normal conditions nitrogen is a colorless, odorless and tasteless gas. Nitrogen makes up around 78% of the air you breathe. Nitrogen is present in all living things, including the human body and plants.
What is nitrogen made up of?
Nitrogen is an element that can combine with itself or with other elements to make different compounds. For instance nitrogen gas, N2, is a compound made when two nitrogen atoms form a chemical bond. It makes up about 80% of the atmosphere, while oxygen gas, O2, makes up a little less than 20% of the atmosphere.
