The HNH angle is 107.8 0
Nitrogen can form three covalent bods.An example is ammonia (NH3) with the bond angle 106,7o.
First, trace amounts of ammonia are everywhere. Second, there is no reason to run and hide from ammonia. Ammonia is nothing to be afraid of.
Ammonia is a compound, not a mixture.
ammonia is basic
The HNH angle is 107.8 0
As of July 2014, the market cap for Handy & Harman Ltd. (HNH) is $323,144,582.81.
The four electron pairs form a basically tetrahedral shape, but with the angles between the bond pairs slightly smaller than the bond pair to lone pair angle. Ammonia has this shape and the HNH angle is 107 degrees. If you only consider the atoms the shape is called trigonal pyramidal.

The airport code for Hoonah Airport is HNH.
Bond angles in various molecules tend to be as big as possible and therefore we would expect a bond angle of 120°. Ammonia, however, is a permanent dipole and therefore acts like it owns a 4th hydrogen atom. Ammonia more or less acts like a tetrahedral molecule. This phenomena occurs in water as well. The theoretical bond angle for a tetrahedral molecule would be 109.5°, but in ammonia it's a little lower, the experimental bond angle of ammonia is 107°. This is because of the additional repulsive force of the electron pair occupying the "fourth" spot of the tetrahedron.

this molecule has a similar shape to ammonia, however the bond angles are less- ammonia is 1070 whereas arsine is only 91 0. Usually it is said that the hybridisation in AsH3 is sp3 (however this would imply a bond angle of 109.5- which is close to the ammonia angle)- however the angle of 91 0 is so close to the angle between the p orbitals (900)that it suggest there is no hybridisation at all, and that the As- H bonds involve only p orbitals.
The symbol for Handy & Harman Ltd. in NASDAQ is: HNH.
Ammonia molecule is Pyramidal because nitrogen in ammonia has 3 bond pairs and one lone pair of electrons, due to presence of lone pair the H-N-H bond angle is about 107 degree less than normal tetrahedral angle 109.5 degree.
in ammonia as N has mre e.n. than H,bond pair of electrons are more towards it which causes repulsion with lone pair of electrons,and they tend o move away but in nf3 bond pair of electrons are away from flourine so they can have lesser bond angle
