Atoms
What is an Atom?
The smallest particle of an element that still has the properties of the element
This is the negatively charged particle
Electron
Tells the number of protons in an element
Atomic number

Protons-6
Neutrons-8
Electrons-6
How are elements organized on the periodic table
By their atomic number
The dense center of the atom is called what?
Nucleus
This is the positively charged particle
Proton
Tells the number of protons and neutrons
Mass number

What are the horizontal rows on the periodic table called
Periods
Also known as energy levels, these break up the region of space surrounding the nucleus
Shells
Where are electrons found
Electron Cloud
How do you know how many electrons are in an element
Same as protons/ atomic number
