Knowing that a no orbital can accommodate more than two electrons,we can predict the maximum number of electrons in each layer or sub-layer ,It is possible <span>when :
* </span>Only two electrons can be assigned to an s orbital<span>.
* </span>three orbitals in a sub-layer p can accommodate two electrons, this sublayer can accommodate a maximum of six electrons.
* The five d orbitals of a sub-layer can accommodate a total of ten electrons.
Example of polar covalent molecules H-O-H(water), ammonia
Explanation:
The presence of intermolecular Hydrogen bonding makes the boiling point of water unexpectedly high, and the polar covalent nature makes it dissolve polar solute/compound
