What is the physical and chemical properties of nitrogen?
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.

Is nitrogen a physical change?
Physical properties Nitrogen changes from a gas into a liquid at a temperature of -195.79°C (-320.42°F) . It changes from a liquid to a solid at a temperature of -210.01°C (-346.02°F). When it freezes, it becomes a white solid that looks like snow. Nitrogen is slightly soluble in water.
What are some of Nitrogens physical properties?
Nitrogen (N2) is a colorless, odorless and tasteless gas that makes up 78.09% (by volume) of the air we breathe. It is nonflammable and it will not support combustion. Nitrogen gas is slightly lighter than air and slightly soluble in water. It is commonly thought of and used as an inert gas; but it is not truly inert.
What are the chemical properties of the nitrogen family?
Here are some facts about the nitrogen family:
- Nitrogen family elements consists of atoms having 5 electrons in their outer energy level.
- As you move down the nitrogen family: atomic radius increases, ionic radius increases, ionization energy decreases, and electronegativity decreases.
What are the properties and uses of nitrogen?
A colourless, odourless gas. 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.

What are the physical and chemical properties of oxygen?
The key properties of oxygen are listed below:
- It is a colorless, odorless and tasteless gas.
- It readily dissolves in cold water.
- It is highly reactive and form oxides with almost all elements except noble gases.
- Liquid oxygen is strongly paramagnetic.
- It exists in three allotropic forms- monoatomic, diatomic and triatomic.
Which is chemical property?
A chemical property is a characteristic of a particular substance that can be observed in a chemical reaction. Some major chemical properties include flammability, toxicity, heat of combustion, pH value, rate of radioactive decay, and chemical stability.
What happens to nitrogen when heated?
When the nitrogen is cold enough to be a liquid, exposure to room temperature air will cause it to boil. As boiling nitrogen heats up and becomes a gas again, it expands.
Can nitrogen become a solid?
At pressures higher than 110 GPa and temperatures around 2000 K, nitrogen forms a network solid, bound by covalent bonds in a cubic-gauche structure, abbreviated as cg-N.
What is the chemical symbol of nitrogen?

What are chemical properties and changes?
The change of one type of matter into another type (or the inability to change) is a chemical property. Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion.
What are physical chemical properties?
Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change. To identify a chemical property, we look for a chemical change.
Does nitrogen pressure change with temperature?
The pressure in nitrogen filled tires will change when the temperature changes, just as it does with air filled tires, because nitrogen and oxygen respond to changes in ambient temperature in a similar manner.
Is nitrogen a liquid solid or gas?
gas
You will find out that nitrogen is a gas at room temperature, and that in order for it to be in a liquid state it must be very cold. When the nitrogen is cold enough to be a liquid, exposure to room temperature air will cause it to boil.
Can nitrogen be a liquid and a gas?
Nitrogen can be a gas or a liquid or a solid. At ordinary pressure, it’s a gas at room temperature. If you get it cold enough, below 77K, it turns into a liquid. A bit colder, below 63K, it turns into a solid.
What happens when nitrogen turns into a liquid?
While nitrogen is a gas at room temperature, it becomes a liquid when cooled down to negative 320 F.
Is nitrogen highly reactive?
Nitrogen is a rather unreactive element, and the reason is that the N≡N bond energy is 946 kJ mol−1. This lack of reactivity is somewhat unlike other nonmetals given the position of the atom in the periodic table and the fact that nitrogen is a nonmetal having an electronegativity of 3.0 (the third highest value).
