What is at the center of the atom
What is the nucleus
Atoms are tiny indivisible particles
What is the main component of the atomic theory
What are protons, neutrons, and electrons
What are the charges of protons, neutrons, and electrons?
What is positive, no charge, and negative
What surrounds the nucleus
What is the electron cloud
Atoms have a dense nucleus that contains protons, neutrons, and electrons
Who is Rutherford
What do atoms make up
What is matter
What is a lepton?
What is an elementary particle. That cannot combine to create a bigger particle. An electron is a type of lepton
Define the atomic theory
The idea that all matter is made up of tiny, indivisible particles called atoms.
What carries the most atomic mass in the atom
What is the nucleus
Electrons move at a fixed rate. Electrons have energy levels
Who is Bohr
What does the atomic theory help us understand
What is to understand the chemical and physical properties of an atom and its behaviour
What is a quark
What is an energy level in an atom?
What is the space surrounding the nucleus where electrons are
What is the size of an atom
What is 0.1 nanometers
Thomson's theory
Atoms have electrons in a positive "pudding"
Electrons have energy levels. And energy levels determine the chemical properties of an atom.
What are valence electrons?
How many types of quarks are there?
6
Why are leptons so important?
What is because they play a key role in the universe's forces (i.e electromagnetism, nucleur fusion)
