Question

What will be the sum of all possible values of L and m for n is is equal to 5

Answer 1

Answer:

• The principle quantum number,or n , describe the energy level in which the electron an be found,since you're interested in an electron located in 5d-orbital,n=5

Answer 2

The sum of all possible values of L and m for n is is equal to $5$ is $10$

Explanation:

• There are four different types of quantum numbers used to decsribe an electron present in an orbital.

• They are Principal quantum number,Azimuthual quantum number,Magnetic quantum number and Spin quantum number.

• Principal quantum number gives us information about the size and energy of the orbital.

• Azimuthual quantum number tells us about the shape of the orbital.

• Magnetic quantum number gives us information about the orientatoon of the orbital where the electron resides.

• When $n=5,l=0,1,2,3,4$

• When $n=5,m=-4,-3,-2,-1,0,1,2,3,4$

• So the sum of all possible values of L and m will be, $n(5)=0+1+2+3+4+0+1+2+3+4+-4+-3+-2+-1=10$
