What are the four quantum numbers and explain what they represent?

Answer 1

Principal - Indicates the main energy level occupied by electrons.

Angular Momentum - Indicates the shape of the orbital.

Magnetic - Indicates the orientation of an orbital around the nucleus.

Spin - Only has 2 possible values, +1/2 and -1/2, which indicates two possible spin states of the electron.

Answer 2

A quantum number is a electron's 'address' Each electron's address is different. This is stated by the Paulli Exclusion Principle.

1st quantum number (principle)- principal energy level: indicates size, the more energy levels the bigger in size

2nd quantum number (azamuthal)-sublevel: indicates shape where s=0, p=1, d=2, and f=3. S orbitals are shaped like a sphere and p orbitals are shaped like an infinity symbol

3rd quantum number-orbital magnetic: show orentation is space

4th quantum number is spin +/- : whether arrow is pointing up or down in orbital

Ex for orbitals

s 0

p -1 0 1

d -2 1 0 1 2

f -3 -2 -1 0 1 2 3

Ex: an address of 3,2,0, +1/2 means that the electron is in the 3rd energy level, is in the 2nd sublevel (because we said that the d=2 up there where it says 2nd quantum number), is in the 0 orbital (remember we said the d sublevel has orbitals -2 -1 0 1 2) and has a positive spin(is the arrow that is pointing up)

Hope this helped a little

Answer 3

The four quantum numbers are principal quantum number (n), azimuthal quantum number (l), magnetic quantum number (m_l), and spin quantum number (m_s). They represent different properties of an electron in an atom - n determines the energy level, l determines the shape of the orbital, m_l determines the orientation of the orbital in space, and m_s determines the electron's spin.
