The Quantum Mechanical Model of an Atom

Front

What is the Quantum Mechanical Model of an atom?

Back

A model that describes the behavior of electrons in atoms using wave characteristics and mathematical concepts.

Front

Who proposed the Quantum Mechanical Model of the atom?

Back

Louise de Broglie and Erwin Schrodinger.

Front

What does the uncertainty principle state?

Back

It is impossible to determine both the momentum and the position of an electron at the same time accurately.

Front

What is the ground state of an electron?

Back

The lowest energy level that an electron normally occupies.

Front

What is the valence shell?

Back

The highest occupied energy level where the last distributed electron(s) are located.

Front

What are valence electrons?

Back

Electrons occupying the valence shell.

Front

What is an atomic orbital?

Back

A region around the nucleus of an atom where you can find electrons with a higher probability.

Front

What is the shape of a Sharp (s) orbital?

Back

It is a spherical cloud.

Front

What is the shape of a Principal (p) orbital?

Back

It is a dumbbell-shaped cloud.

How many types of p orbitals are there?

Back

There are three types: px, py, and pz.
