Quantum Numbers Flashcard 1

Front

What does the principal quantum number (n) indicate in an atom?

Back

The principal quantum number (n) indicates the energy level of an electron in an atom.

Front

What are the four quantum numbers used to describe an electron in an atom?

Back

The four quantum numbers are: principal quantum number (n), azimuthal quantum number (l), magnetic quantum number (m_l), and spin quantum number (m_s).

Front

What does the azimuthal quantum number (l) represent?

Back

The azimuthal quantum number (l) represents the subshell or shape of the orbital (e.g., s, p, d, f).

Front

What is the range of values for the azimuthal quantum number (l)?

Back

The azimuthal quantum number (l) can take on integer values from 0 to n-1, where n is the principal quantum number.

Front

What does the magnetic quantum number (m_l) indicate?

Back

The magnetic quantum number (m_l) indicates the orientation of the orbital in space.

Front

What is the range of values for the magnetic quantum number (m_l)?

Back

The magnetic quantum number (m_l) can take on integer values from -l to +l.

Front

What does the spin quantum number (m_s) represent?

Back

The spin quantum number (m_s) represents the intrinsic spin of an electron, which can be +1/2 or -1/2.

Front

What is the significance of the quantum number set (n, l, m_l, m_s) for an electron?

Back

The set of quantum numbers uniquely identifies the state of an electron in an atom.

Front

What is the shape of an s orbital?

Back

The shape of an s orbital is spherical.

Front

What is the shape of a p orbital?

Back

The shape of a p orbital is dumbbell-shaped.
