Lesson 1 - Electron Configuration

What does the Quantum Mechanical Model of electrons within an atom state?

• Electrons are organized in specific rings around the nucleus

• We can only get the probability of where the electron is

• We can pinpoint the exact location of an electron

• Electrons are distributed randomly within an atom

What do principal energy levels describe?

• The speed of electrons within an atom

• The average distance of an electron from the nucleus

• The arrangement of electrons in an atom

• The number of protons in an atom
