explain the formation of NH3 and H2O molecules .give me answer don't give link
Formation of NH3
One nitrogen atom consist of 5 outer electron and one hydrogen atom consist of one outer electron. Out of the 5 electron , three electron of nitrogen atomcombine 3 hydrogen atom containing one elctron each to form three single bonds as shown in the figure. Thus, according to this nitrogen left with one lone pair of electron to form a pyramidal NH3 molecule.
Formation of H2O
Oxygen consist of 6 outer electron and two out of which form two single covalent bond with the one outer electron hydrogen atom. This result in the formation of water molecule having bent shape due to the presence of two lone pair of electrons
In higher classes you will study about the different theories like valence bond theory which will explain the formation of these two molecules.
