1.	Assertion : The energy of an electron is largely determined by its principal quantum number. Reason : The principal quantum number n is a measure of the most probable distance of finding the electron around the nucleus.A. If both assertion and reason are true and the reason is the correct explanation of the assertionB. If both assertion and reason are true but reason is not the correct explanation of the assertionC. If assertion is true but reason is falseD. If the assertion and reason both are false
Answer» Correct Answer - A We know that principal quantum number represent the main energy level or energy shell. Since each energy level is associated with a definite amount of energy, this quantum numbers determines to a large extent energy of an electron. It also determines the average distance of an electron around the nucleus . Therefore both Assertion and Reason are true and the Reason is a correct explanation of the Assertion.
