Periodic Table of Elements
![Page 2: Periodic Table of Elements. Elements are types of atoms! Elements can not be broken down into simpler substances. Everything is made of matter = atoms.](https://reader031.fdocuments.in/reader031/viewer/2022020208/56649f465503460f94c67d95/html5/thumbnails/2.jpg)
Elements are types of atoms!
• Elements can not be broken down into simpler substances.
• Everything is made of matter = atoms.

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

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
