Answer: The ground condition and excited state outer electronic configurations of phosphorus (Z = 15) are:
because the addition of a number of electrons would cause greater repulsion One of the electrons along with a minimize in powerful nuclear charge.
(ii) It will be the duty of the Head of The varsity to make sure marketing from Class XI to Class XII on The premise from the cumulative accomplishment level of the applicant all through the academic 12 months inside the subjects the candidate continues to be registered for.
Whereas, electron obtain enthalpy is the tendency of an atom to bring in outdoors electron. It is the house of the isolated atom.
Remedy: Every time a chemical bond is fashioned by the complete transfer of electrons from one particular atom to another, so as to complete their outermost shell and as a consequence, aquire the stable noble fuel configuration, the bond fashioned is termed ionic bond or electrovalent bond. ‘
(d) Give the total number of the kind of tooth stated in 'one' earlier mentioned, from the mouth of an Grownup and point out its purpose.
