Quantum Mechanical Model of the Atom

Question 1

Louis de Broglie discoveries

Answer 1

• Electrons do not move in simple defined orbits
• Electrons move in circular standing waves
• # of wavelengths must be whole number integers

Question 2

What did SchrOdinger do?

Answer 2

• Wrote the wave equation to predict the location of electrons within an atom

Question 3

What is an orbital?

Answer 3

Regions in 3D space where an electron can be found 90% of the time

Question 4

What is a wave function?

Answer 4

Mathematical probability of finding an electron in a certain region of space

Question 5

Heisenberg’s Uncertainty Principle

Answer 5

• Due to the wave and particle nature of matter, it is impossible to predict the position and momentum of an electron
• Only describe a region of probability of finding an electron
