Agriculture and Industry - Nitrogen and Group 5

Electronic configuration:

• Nitrogen: [He] 2s^2 2p^3                            Total number of electrons = 7
• Phosphorus: [Ne] 3s^2 3p^3                      Total number of electrons = 15
• Arsenic: [Ar] 3d^10 4s^2 4p^3                   Total number of electrons = 33
• Antimony: [Kr] 4d^10 5s^2 5p^3                Total number of electrons = 51
• Bismuth: [Xe] 4f^14 5d^10 6s^2 6p^3       Total number of electrons = 83

Nitrogen and group 5 - extra info:

• Nitrogen and phosphorus are non-metals and antimony and bismuth are metalloids (metallic elements with some non-metal character)
• Atoms of these elements can form 3 covalent bonds by sharing the 3 unpaired electrons
• Oxidation state of the group 5 element is +3 or -3
• Each atom has a lone pair of electrons => dative covalent bonds, with oxidation state of +5
