Three quantum numbers are derived from Schrodinger’s equation that describe the probability of finding an electron around a nucleus: the principal quantum number, the angular momentum quantum number, and the magnetic quantum number. Explain each quantum number, including associated shapes, numbers, letters and values. (please help)

Principal Quantum Number (n) = energy level (1s2)

Angular Momentum Quantum Number (l) = sub-shell (1s2)

Magnetic Quantum Number (mi) = specific orbital electron occupies

range of (n) = 1-7

range of (I) = s, p, d , f

Explanation:

Principal Quantum Number: designates the principal electron shell. Angular Momentum Quantum Number-This quantum number determines it's shape of an orbital and thus it's angular distribution. This quantum number determines the number of orbital numbers, their orientation within the sub-shell.

Principal Quantum Number, n

It describes the size of its orbital and of the main energy level. It is represented by n. Where, n = 1,2,3,4stands for K, L, M, N shell and so on..  

ngular Momentum Quantum Number l

It describes the shape of the orbital and thus the angular distribution. It can take  from 0 to (n - 1). That is l = 0,1,2,...,(n - 1)

The magnetic Quantum Number, m

It describes the orientation of the orbitals. It is represented as . The value of this quantum number ranges from . When l = 2, the value of  will be -2, -1, 0, +1, +2.

Explanation:

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles

hope this !

and sorry if i'm late. have a good rest of your day! : d
