What is the evidence from Thomson's experiment that all atoms contain electrons?
- ANSWER ✓ The particles are identical regardless of the identity of the
cathode(where they were emitted from).
What is an alpha particle? - ANSWER ✓ Has 2 protons and 2 neutrons. It is the
nucleus of a Helium atom.
Coulomb's Law - ANSWER ✓ Negative and positive charges attract and like
charges repel.
4 Types of Forces - ANSWER ✓ Gravitational, Electromagnetic, Strong Nuclear,
Weak Nuclear
Gravitational Force - ANSWER ✓ Responsible for attraction between objects that
have mass.
Electromagnetic Force - ANSWER ✓ Responsible for attraction/repulsion for
objects that have an electric charge.
Kinetic Energy - ANSWER ✓ The energy associated with motion.
Potential Energy - ANSWER ✓ The energy associated with the position of a
system of objects in a field.
London Dispersion Forces - ANSWER ✓
, How many molecules must be present for LDF's to exist? - ANSWER ✓ Two or
more
