Understanding the Electronic Structure of Matter

What are the three subatomic particles that make up an atom?

• Neutrons, quarks, and photons

• Electrons, photons, and quarks

• Protons, neutrons, and electrons

• Protons, neutrons, and photons

How do electrons determine the way atoms interact and bond?

• By their mass

• By their charge

• By their speed

• By their color

What does the electron configuration of an atom describe?

• The number of protons in the nucleus

• The arrangement of electrons in an atom

• The color of the atom

• The mass of the atom

How are elements organized in the periodic table?

• By their atomic mass

• By their color

• By their size

• By their electron configurations and properties

What role does quantum mechanics play in understanding electronic structure?

• It organizes the periodic table

• It explains the color of atoms

• It describes the mass of electrons

• It provides a framework for understanding particle behavior as waves and particles
