What is a N2 molecule?
Molecular nitrogen (N2) is a very common chemical compound in which two nitrogen atoms are tightly bound together. Molecular nitrogen is a colorless, odorless, tasteless, and inert gas at normal temperatures and pressures. Four representations chemists use for nitrogen molecules.
Why is nitrogen written as N2?
N2 Leweis Structure
The N2 molecule is diatomic, meaning that two atoms of the same element are connected in a pair.
What type of bond is N2?
Nitrogen has a triple covalent bond. Nitrogen is non metal. The outer shell of a nitrogen atom contains 5 electrons. Two nitrogen atoms share three electrons each, forming three covalent bonds and making a nitrogen molecule N2.
What is the molecular geometry shape of H2S?

What is the geometry and shape of H2S?
The molecular shape of hydrogen sulphide molecule, H2S is bent or V shaped, with 92 degree bond angle.
What is the molecular geometry around an atom in a molecule or ion which is surrounded by two lone pairs of electrons and three single bonds?
If these are all bond pairs the molecular geometry is tetrahedral (e.g. CH4). If there is one lone pair of electrons and three bond pairs the resulting molecular geometry is trigonal pyramidal (e.g. NH3). If there are two bond pairs and two lone pairs of electrons the molecular geometry is angular or bent (e.g. H2O).
What is the geometry around the nitrogen carbon α and carbon?
