NH3 is basic while BiH3 is only feebly basic because:
1) the atomic size of N is less than Bi.ther fore it has smaller size than Bi.
2)the electron density of N is much more than Bi due to small size.
3)therfore because of small size and high electronegativity of N the tendancy to
donate its lone pair of electon in NH3 will be much higher than Bi in BIh3.
In NF3, the bond angles are larger than in NH3.
NH3 is more polar than NF3 because a) there is a greater difference in electronegativity between nitrogen and hydrogen than there is between nitrogen and fluorine. b) the lone pair contribution in ammonia reinforces the dipole wheras in NF3 the bond dipoles oppose th effect of the lone pair
NH3 can act as a weak Bronsted base in water because it can accept a proton to form the NH4+ ion. NF3, on the other hand, does not readily accept protons in water due to the presence of fluorine atoms that strongly attract electrons, making it less basic than NH3. The electron-withdrawing nature of the fluorine atoms in NF3 reduces its ability to donate electrons and act as a base.
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
NF3 (nitrogen trifluoride) is a covalent compound. It is formed through the sharing of electrons between nitrogen and fluorine atoms, resulting in a stable molecule with a molecular structure held together by covalent bonds.

Ammonia: -33,34 0C Nitrogen trifluoride: -129 0C
This is because in ammonia the direction of resultant dipole is towards lone pair and hence it has high dipole moment but in case of NF3 the direction of resultant dipole moment is opposite to the lone pair and hence the dipole moment gets less.
Boiling point of NH3: -33,34 0C Boiling point of NF3: -129,1 0C The boiling point of ammonia is higher.
It stands for Ammonia.A basic gaseous compound.
Hydroxide ion (OH-) is a basic substance because it can accept protons (H+) to form water (H2O). In terms of basicity, molecules like NH3 (ammonia) or CH3NH2 (methylamine) are more basic than OH because they can accept protons more readily.
PH3 (phosphine) is considered to be a weaker base compared to NH3 (ammonia) because the electronegativity of phosphorus is greater than nitrogen, making the lone pair on phosphorus less available for donation. This results in NH3 being a stronger base than PH3.
Milk of magnesia contains MgO. It is more basic than NH3.
