Question

8. Write the symbol for the principal quantum number. What is its range of possible values? What information does it contain?

9. Write the symbol for angular momentum quantum number. What is the range of possible values? What information does it contain?

10. Write the symbol for the magnetic quantum number. What is its range of possible values? What information does it contain?

11. Write the symbol for the spin quantum number. What is its range of possible values? What information does it contain?

Answer 1

1. Principal quantum number = n

Range of possible value = 0, 1, 2, 3, 4, …∞

Information = provides information about the energy of an electron and the size of the orbital.

2. Angular momentum quantum number = l

Range of possible value = 0, 1, 2, …(n-1)

Information = provides information about the type or shape of the orbital where there is a maximum probability of an electron to reside.

3. Magnetic quantum number = m_l

Range of possible value =   -l, ..., 0, ..., +l.

Information = provides information about the orientation in space of an orbital in which the electron resides.

4. Spin quantum number = m_s

Range of possible value = +½ or -½

Information = provides information about the orientation of the spin axis of an electron.
