Both PH3 and NH3 have 3 bonding pairs and 1 lone pair of electrons around the central atom, and so are both trigonal pyramidal in shape. The bond angle in NH3 is less than 109.5º and that in PH3 is less than that in NH3 (maybe around 109º). The reason for this has to due with electronegativity. The N atom is more electronegative than the P atom and thus electron density of N's bonding electrons are closer to the N, and so they exert a greater repulsion on each other. This greater repulsion compared to that seen PH3 makes the bond angle slighter greater in NH3. P being less electronegative than N doesn't draw it's electrons as close so they don't repel as much.

Why ammonia has larger bond angle than nf3?
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
What is the bond angle between the hydrogen atoms in an ammonia NH3 molecule?
The bond angle between the hydrogen atoms in an ammonia (NH3) molecule is approximately 107 degrees.
How do the bond angles in NF3 compare to those in NH3?
In NF3, the bond angles are larger than in NH3.
What is the chemical bonding of ammonia?
Ammonia (NH3) has a covalent bond where the nitrogen atom shares its electrons with three hydrogen atoms. This results in a molecule with a trigonal pyramidal shape. The bond angle between the hydrogen atoms is approximately 107 degrees.
Does NH3 contain a nonpolar covalent bond?
No, NH3 does not contain a nonpolar covalent bond. The bonds in NH3, which are between nitrogen and hydrogen atoms, are polar covalent because nitrogen is more electronegative than hydrogen, causing an uneven distribution of electrons.
Is NH3 a 180 degree angle?
No, the bond angles in NH3 are approximately 107 degrees.
Why is the bond ch4 larger than the bond angle in nh3?
Santa clause crawled into my bed and told me because he said so

How do the bond angles in NF3 compare to those in NH3?
In NF3, the bond angles are larger than in NH3.
Bond angle of NH3?
107.5 approximately, as the molecule is based on a tetrahedral shape, which should have 109.5 degree bonds, but the lone pair on the N causes the bond angles to be slightly decreased, by about 2 degrees
What is the chemical bonding of ammonia?
Ammonia (NH3) has a covalent bond where the nitrogen atom shares its electrons with three hydrogen atoms. This results in a molecule with a trigonal pyramidal shape. The bond angle between the hydrogen atoms is approximately 107 degrees.
Which molecule has 120 degrees bond angle?
A trigonal planar molecule such as sulfur trioxide (SO3) or boron trihydride (BH3) has a trigonal planar shape. Trigonal pyramidal molecules such as ammonia (NH3) have bond angle closer to 107 degrees.
Does NH3 contain a nonpolar covalent bond?
No, NH3 does not contain a nonpolar covalent bond. The bonds in NH3, which are between nitrogen and hydrogen atoms, are polar covalent because nitrogen is more electronegative than hydrogen, causing an uneven distribution of electrons.
What is the maximum number of covalent formed by nitrogen?
Nitrogen can form three covalent bods.An example is ammonia (NH3) with the bond angle 106,7o.
What is the bond between NH3 and BF3 called?
The bond between NH3 and BF3 is called a coordinate covalent bond or a dative bond. In this type of bond, both electrons are provided by one atom (in this case, NH3) to form a shared pair with the other atom (BF3).
What is the bond energy of nh3?
The bond energy of NH3, which is the energy required to break one mole of NH3 molecules into its individual atoms, is approximately 391 kJ/mol.
