Key Stage 3
Meaning
Nitrogen is a Group 5 non-metal element, on the Periodic Table, with an atomic number of 7.
About Nitrogen
- Nitrogen makes up 78% of the air.
- Nitrogen has the chemical symbol N.
Molecular Structure
- The chemical formula for a Nitrogen molecule is N2.
Atomic Structure
- Nitrogen has 7 protons and 7 neutrons in its nucleus giving it an atomic number of 7 and a atomic mass of 14.
- Nitrogen is in Period 2 of the Periodic Table because it has 2 electron shells.
Properties
Key Stage 4
A 2 dimensional representation of the Bohr Model of a Nitrogen-14 isotope with 7 protons and 7 neutrons in the nucleus and 2 electrons in the first shell and 5 in the outer shell.
Meaning
Nitrogen is a Group 5 non-metal element, on the Periodic Table, with 7 protons in the nucleus.
About Nitrogen
- Nitrogen makes up 78% of the air.
- Nitrogen has the chemical symbol N.
Molecular Structure
- The chemical formula for a Nitrogen molecule is N2.
- Nitrogen forms a covalent bond with another Nitrogen atom to produce a simple covalent molecule.
Atomic Structure
- The most common stable isotope of Nitrogen has 7 neutrons in its nucleus giving it an atomic mass of 14.
- Nitrogen is in Period 2 of the Periodic Table because it has 2 electron shells.
- Nitrogen has 5 electrons in its outer shell and needs 3 more electrons to get a full outer shell so it can form 3 bonds with other atoms.
