Exploring Electron Configuration and Orbital Notation

According to the Aufbau principle, in what order do electrons fill orbitals?

• From lowest to highest energy

• Based on atomic number

• Randomly

• From highest to lowest energy

What does the Pauli exclusion principle state about electrons in an orbital?

• Electrons fill orbitals in pairs

• Electrons in an orbital must have the same spin

• An orbital can hold a maximum of two electrons with opposite spins

• An orbital can hold any number of electrons

What is Hund's rule also known as?

• Shoe box rule

• Parallel spin rule

• Lowest to highest rule

• Kids with candy rule

What does the Heisenberg uncertainty principle imply about measuring electrons?

• It is impossible to know the exact position and velocity of an electron simultaneously

• Electrons do not have a definite position

• It is possible to know both the position and velocity of an electron

• Electrons move in predictable paths
