What is the atom of nitrogen?
In the Bohr model, a nitrogen atom has a central nucleus, composed of seven protons and seven neutrons, surrounded by seven electrons. Two of the electrons are in the first energy level while the other five are in the second energy level.
Nitrogen itself is an element. But nitrogen is found as N2 in nature. A compound is a molecule that contains at least two different elements (i.e. water) while a molecule is formed when two or more atoms join chemically. All compounds are molecules but not all molecules are compounds.
- 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.
- A molecule is the smallest particle of a substance that exists independently. Molecules of most elements are made up of only one of atom of that element. Oxygen, along with nitrogen, hydrogen, and chlorine are made up of two atoms. The oxygen molecules are bonded or stuck together.
- So for the element of NITROGEN, you already know that the atomic number tells you the number of electrons. That means there are 7 electrons in a nitrogen atom. Looking at the picture, you can see there are two electrons in shell one and five in shell two.
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.
- Nitrogen-fixing bacteria, microorganisms capable of transforming atmospheric nitrogen into fixed nitrogen (inorganic compounds usable by plants). Within the nodules the bacteria convert free nitrogen to ammonia, which the host plant utilizes for its development.
- 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
- 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.
N2 is the formula of the nitrogen molecule, which has two atoms of nitrogen in it.. The nitrogen gas exists only as N2 molecules in free state.
- 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.
- It is also used in various industries. For example, in the chemical industry is used to make fertilizers, nitric acid, nylon, dyes and explosives. For making these products, it is imperative for nitrogen to react with hydrogen to produce ammonia. Here are the five applications of nitrogen in everyday life.
- Nitrogen was discovered by the Scottish physician Daniel Rutherford in 1772. It is the fifth most abundant element in the universe and makes up about 78% of the earth's atmosphere, which contains an estimated 4,000 trillion tons of the gas.
