# Quick Answer: Which Of The Following Sets Of Quantum Number Is Correct?

## Which of the following sets of quantum numbers are allowed?

Rules Governing the Allowed Combinations of Quantum Numbers The angular quantum number (l) can be any integer between 0 and n – 1.

If n = 3, for example, l can be either 0, 1, or 2.

The magnetic quantum number (m) can be any integer between -l and +l.

If l = 2, m can be either -2, -1, 0, +1, or +2..

## Which of the following sets of quantum number is correct for an electron in 3d orbital?

## What is the quantum number of chromium?

The correct quantum numbers for the last electron in Chromium: \$Cr = [Ar] 3d^{5} 4s^{1}\$ Thus n =3, l = 2, m = +2, s = +1/2 Also, if these same quantum numbers are used, it is the same with the last quantum number of manganese.

## What is magnetic orbital quantum number?

Magnetic Quantum Number (ml): ml = -l, …, 0, …, +l. Specifies the orientation in space of an orbital of a given energy (n) and shape (l). This number divides the subshell into individual orbitals which hold the electrons; there are 2l+1 orbitals in each subshell.

## What quantum number indicates the position of an orbital?

The principal quantum number just indicates the size of the orbital or energy level, the angular momentum quantum number indicates the shape of the orbital, the magnetic quantum number indicates the orientation or position of the orbital, and the spin quantum number indicates the spin of the electron, represented as …

## What does the magnetic quantum number ml refer to?

MAGNETIC QUANTUM NUMBER (ml) Designates the orbital (room) where the electron can be found. • Gives the DIRECTION IN SPACE that the orbital takes. • ml specifies to which orbital within a subshell the electron is assigned.

## Which of the following set of quantum number is correct?

If n = 3, l= 0, 1,2. For l = 2, m = -2, -1, 0, +1, +2. Hence (c) is correct.

## What does principal quantum number describe?

The principal quantum number n represents the relative overall energy of each orbital. The energy level of each orbital increases as its distance from the nucleus increases. … based on the principal quantum number.

## What are the four quantum number of 19th electron of copper?

(i) 19th electron of . 24C. n=4,l=0,m=0,s=+12or-12. (ii) 21st electron for .

## How many electrons does an atom have May?

How many electrons in an atom may have the following quantum numbers? (a) n = 4, (b) n = 3, l = 0. b) When n= 3, l=0 means 3s orbital which can have 2 electrons .

## Which quantum set is not possible?

This set of quantum numbers is not possible. n=2,l=1,ml=0,ms=+1/2; All the values according to rules n=3,l=1,ml=0,ms=+1/2; All the values according to rules.

## Which of the following sets of quantum numbers is not possible?

For option C), the angular momentum quantum number of equal to ++2, which means that ml can have a maximum value of +2. Since it is given as having a value of +3**, this set of quantum numbers is not a valid one. The other three sets are valid and can correctly describe an electron.

## Which of the following set of quantum numbers is correct for the 19th electron of chromium?

The nineteenth electron of chromium has which of the following set of quantum number? Solution : 19th electron of Cr or any7 other atom goes to 4s orbital. Hence correct is 4, 0, 0, ±12.

## What are the four quantum numbers of the 19th electron in SC Z 21?

Answer. the ans is n =4,l=0,m=0,s=+1/2.

## Which is a set of quantum numbers for an electron in a 4f orbital?

Similarly, you may ask, which set of quantum numbers describes a 4f orbital? In this notation for orbitals, (1s, 2s, 3d, etc.) the number always refers to n, the principle quantum number. So in the case of a 4f orbital, we have n=4.

## What three quantum numbers are associated with the 4d orbital?
