How many electrons can be held in a single atomic orbital?

• 1

• 2

• 4

• 8

What is a sublevel in the context of atomic structure?

• A type of chemical reaction

• A division of energy levels in an atom

• A type of atom

• A type of molecule

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

• We can pinpoint exactly where an electron is.

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

• Electrons are stationary within an atom.

• Electrons have fixed orbits.

What do electron configurations show?

• The exact speed of electrons.

• How electrons are distributed within an atom.

• The color of electrons.

• The size of electrons.

What is the traditional model of an atom as described in the image?

• An atom with a single center and rings around it

• An atom with multiple centers and no rings

• An atom with no center and scattered particles

• An atom with a single center and no rings

What do the principal energy levels (n=1, 2, 3, 4, etc.) describe in an atom?

• The color of the atom

• The average distance of an electron from the nucleus

• The number of protons in the nucleus

• The shape of the electron cloud

How does energy change as you move further from the nucleus in an atom?

• Energy decreases

• Energy remains constant

• Energy increases

• Energy fluctuates randomly

What do electrons occupy within each energy level?

• Orbits

• Sublevels

• Nuclei

• Protons

What do sublevels correspond to in an atom?

• The number of protons in the nucleus

• The different areas an electron can be located

• The total mass of the atom

• The number of neutrons in the nucleus
