1.	Assertion. Electronic configurations of Cr^(3+) (containing 21 electrons) is same as that of Sc (Z = 21), i.e., isoelectronic species have the same electronic configuration Reason. Orbitals of atoms as well as ions are filled in order of increasing energy following aufbau principle
Answer» If both ASSERTION and reason are true, and reason is the true explanation of the arrertion If both assertion and reason are true, but reason is not the true explanation of the assertional If assertion is true, but reason is false If both assertion and reason are false Solution :Correct A. Atomic and cations containing the same number of electrons do not have the same electronic configuration Correct R. Orbitals of ATOMS are filled in order of increasing energy.
