1 Periodic Table of Elements

2 Elements are types of atoms!
Elements can not be broken down into simpler substances. Everything is made of matter = atoms.

3 What do atoms look like? Protons (+) Neutrons Electrons (-)
Positive charge Located in the nucleus The number of protons = the signature of the atom. Neutrons No charge Electrons (-) Negative charge Located in the electron cloud (electron orbitals) 2, 8, 18, 36 Super small compared to protons and neutrons.

4 What makes one type of atom different from another?

5 What does the periodic table tell you?
Atomic Number = Number of Protons Tells what type of atom you have. Tells the number of electrons in an electrically neutral atom. Atomic Mass = # of protons + # of neutrons Mass of nucleus

6 Protons = ____________ Neutrons= ___________ Electrons =___________ Draw the Bohr Model

7 Protons = ___________ Neutrons = __________ Electrons = ___________ Draw the Bohr Model
