What is positive, no charge, and negative

200

What surrounds the nucleus

What is the electron cloud

200

Atoms have a dense nucleus that contains protons, neutrons, and electrons

Who is Rutherford

200

What do atoms make up

What is matter

200

What is a lepton?

What is an elementary particle. That cannot combine to create a bigger particle. An electron is a type of lepton

200

Define the atomic theory

The idea that all matter is made up of tiny, indivisible particles called atoms.

300

What carries the most atomic mass in the atom

What is the nucleus

300

Electrons move at a fixed rate. Electrons have energy levels

Who is Bohr

300

What does the atomic theory help us understand 

What is to understand the chemical and physical properties of an atom and its behaviour 

300

What is a quark

What is an elementary particle. That makes up protons and neutrons. It helps hold together the nucleus 
300

What is an energy level in an atom?

What is the space surrounding the nucleus where electrons are

400

What is the size of an atom

What is 0.1 nanometers

400

Thomson's theory

Atoms have electrons in a positive "pudding"

400
Why are electrons important?

Electrons have energy levels. And energy levels determine the chemical properties of an atom.

400

What are valence electrons?

What is the outermost electrons. That can be shared, lost, or gained
500

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)
