Question

4. Which of the following is/are true a) Multiplicity in Fe3+ is greater than in Co3+ b) Ti3+, Cr+, Sc2+ ions are diamagnetic c) value of (n+l+m)for last electron of mg is 3 d) The value of Zeff for 3s electron of Cl is 10.9



plz explain every option​

Answer 1

The statement which is true is Ti3+, Cr+, Sc2+ ions are diamagnetic  and value of (n+l+m)for last electron of mg is 3

Option b and c

Explanation:

• Quantum numbers are those numbers which are the solution of the set of numbers which can be added in the strodingers wave equation

• There are three basic types of quantum number in case of an atom according to modern concept of chemistry.

• The three types of quantum number are principal quantum number, azimutual quantum number and spin quantum number.

• The spin quantum number can be positive in case of a anticlockwise spin of the electron or negative in case of a clockwise spin of the electrons.

• The principal quantum number is the serial number of the the shell in which the electron is present. It can have its value of one for K Series, two for L series and so on.

• The azimuthal quantum number has a value of zero for S orbital, one for P orbital, two for D orbital and 3 for f orbital.
