Atoms and Matter

What are quarks?

Elementary particles that are indivisible

U: up

C: charm

T: top

D : down

S: strange

B: bottom

What are leptons?

Leptons are a certain type of particle in an electron

What are the differences between subatomic and elementary particles?

Subatomic particles can be separated into smaller particles, while elementary particles are indivisible.

What are protons and neutrons made out of?

Pro: 2 up 1 down

Neu: 2 down 1 up

How does the position on a periodic table help you predict an elements ion charge?

The family/group tells valence electrons and this determines their charge

What is the correct order?

Valence shell

Neutrons

Electrons

Protons

Atomic number

Atomic mass - Atomic number

The number of electrons that has changed

What is non-metal/Metal/Metalloid?

How will the position of the periodic table help you predict its reactivity?

The reactivity depends on how close to full valence shell because atoms will gain or lose electrons to become stable.
