Which of the following statements about electronic configurations of atoms and mononuclear ions, and atomic orbital quantum numbers, are true or false. Fe3+ has the same electronic configuration as V. Sr2+ has the same electronic configuration as Kr. The magnetic quantum number is always an odd number. The valence electronic configuration of bromine is 4s24p5. The value of ℓ is always equal to n minus one.

Electronic configuration is defined as the arrangements of electron present in an element around various shell Each orbital can have maximum of 2 electron The electron placed in orbital are arranged in the increasing order of energy according to Aufbau principle Element atomic number number of electron electronic configuration Vanadium V 23 23 [Ar]4s23d3 Bromine Br 35 35 [Ar]3d104s24p5 Krypton kr 36 36 [Ar]3d104s24p6 Fe3+ 26 23 [Ar]4s23d3 Sr2+ 38 36 [Ar]3d104s24p6The 4 set of quantum number A) principle quantum number is denoted by n and it represent the size of the orbitAl and have values from +1 to any integer B) angular quantum number denoted by l it represent the shape of the orbital and value of l will be less than n C ) magnetic quantum number m is used to describe the orientation of the orbital and value of m is from -l to +l It can any integer value between the range depending on the value of l D) spin quantum number is denoted by ms and it shows the spin of electron and have only two value +1/2 and -1/2 A) the statement Fe3+ has the same electronic configuration as V is true B) the statement Sr2+ has the same electronic configuration as Kr is trueC)The statement The magnetic quantum number is always an odd number is false D) the statement The valence electronic configuration of bromine is 4s24p5 is true E) the statement The value of ℓ is always equal to n minus one is false because for 4p The value of n=4 but the value of l is 1 So it not n-1 always
