structure of a nitrogen atom

Arrangement of Electrons in an Atom (Bohr-Bury Scheme) - Electrons revolve around the nucleus in different energy levels or shells and each shell is associated with definite energy. The energy of the K shell is the least while those of L, M, N and O shells increases progressivel..

>The mass of electrons is negligible compared to the mass of the protons. Ordinary hydrogen is the only element that has no neutron in it. According to Bohr electrons revolve around the nucleus in fixed orbits called K, L, M, N etc. The energy of the shells increases as the distance form ..

Structure - Organic cyanides has a triple bond between the C and N atoms i.e., one sigma and two pi bonds are present. Thus nitrogen here is sp hybridized. The C-C N bond angle is 180 o . Bond length of then the triple bond C N is shorter ..

All these hydrides are covalent in nature and have pyramidal structure. These involve sp 3 hybridization of the central atom and one of the tetrahedral position is occupied by a lone pair. Shape of NH 3 molecule Due to the presence of lone pair, the bond angle in NH 3 is..
