Bohr/Quantum Mechanical Model

Front

Who developed the quantum mechanical model of the atom?

Back

Erwin Schrodinger

Front

What is the shape of the d orbitals?

Back

The d orbitals have complex shapes, often described as cloverleaf or double dumbbell shapes.

Front

How many total orbitals are present in the d subshell?

Back

There are 5 d orbitals in the d subshell.

Front

What does the principal quantum number (n) indicate?

Back

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

Front

What is the magnetic quantum number (ml) used for?

Back

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

Front

What does the angular momentum quantum number (l) represent?

Back

The angular momentum quantum number (l) represents the shape of the orbital.

Front

State Heisenberg's Uncertainty Principle in terms of position and velocity.

Back

Heisenberg's Uncertainty Principle states that it is impossible to know both the velocity and the position of a particle at the same time.

Front

What is the maximum number of electrons that can occupy a single orbital?

Back

A single orbital can hold a maximum of 2 electrons.

Front

What is the significance of the quantum number 'ms'?

Back

The quantum number 'ms' represents the spin of the electron, which can be +1/2 or -1/2.

Front

Which quantum number cannot be negative?

Back

The principal quantum number (n) cannot be negative; it must be a positive integer.
