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 chargeLocated in the nucleusThe number of protons = the signature of the atom.NeutronsNo chargeElectrons (-)Negative chargeLocated in the electron cloud (electron orbitals)2, 8, 18, 36Super 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 ProtonsTells what type of atom you have.Tells the number of electrons in an electrically neutral atom.Atomic Mass = # of protons + # of neutronsMass of nucleus
6 Protons = ____________ Neutrons= ___________ Electrons =___________ Draw the Bohr Model
7 Protons = ___________ Neutrons = __________ Electrons = ___________ Draw the Bohr Model
