Quantum Numbers

Front

What is the principal quantum number (n) and what does it represent?

Back

The principal quantum number (n) indicates the main energy level of an electron in an atom and can take positive integer values (1, 2, 3, ...).

Front

What is the azimuthal (angular momentum) quantum number (l) and how is it determined?

Back

The azimuthal quantum number (l) determines the shape of the electron's orbital and can take integer values from 0 to (n-1).

Front

What does the magnetic quantum number (m_l) represent?

Back

The magnetic quantum number (m_l) indicates the orientation of the orbital in space and can take integer values from -l to +l.

Front

What is the spin quantum number (m_s) and what values can it take?

Back

The spin quantum number (m_s) describes the intrinsic spin of an electron and can take values of +1/2 or -1/2.

Front

How do you determine the maximum number of electrons in a shell based on the principal quantum number (n)?

Back

The maximum number of electrons in a shell is given by the formula 2n².

Front

What is the relationship between the principal quantum number (n) and the energy of an electron?

Back

As the principal quantum number (n) increases, the energy of the electron also increases, indicating that electrons in higher shells have more energy.

Front

What is the significance of the azimuthal quantum number (l) in determining the type of orbital?

Back

The azimuthal quantum number (l) determines the type of orbital: s (l=0), p (l=1), d (l=2), f (l=3).

Front

What is the range of possible values for the magnetic quantum number (m_l) when l=2?

Back

When l=2, the possible values for m_l are -2, -1, 0, +1, +2.

Front

How does the spin quantum number (m_s) affect the electron configuration of an atom?

Back

The spin quantum number (m_s) allows for two electrons to occupy the same orbital, provided they have opposite spins.

Front

What is the relationship between the quantum numbers and the electron configuration of an atom?

Back

Quantum numbers describe the energy levels, shapes, orientations, and spins of electrons, which together define the electron configuration of an atom.
