Q&A

Why doesn't gravity hold the protons and neutrons in the nucleus together?

—Gravity is not strong enough to overcome the repulsion between protons, which have equal electric charges.

What are the properties of quarks?

—Quarks have fractional electric charges and come in different flavors, such as up, down, strange, charm, top, and bottom.

How does the wave function concept explain the behavior of particles?

—The wave function describes the probabilities of various outcomes when measuring the properties of particles, such as spin.

What is Pauli's exclusion principle?

—Pauli's exclusion principle states that no two identical fermions can occupy the same quantum state, leading to the anti-symmetry of wave functions.

Why is understanding atomic physics important?

—Understanding atomic physics helps us unravel the fundamental forces and particles that govern the universe and enables advancements in various fields, such as technology and energy.
