HW Organizing the Elements handout Happy Vernal Equinox

HW: Organizing the Elements handout. Happy Vernal Equinox! Do Now: 3/20/17 Answer the following question on your handout: 1)List the three kinds of particles that make up atoms and their charges. 2) Make a drawing showing their location in the atom.

List the three types of particles that make up an atom: 1. protons 2. neutrons 3. electrons Drawing of your atom

Protons, Electrons and Neutrons PROTON: Positive Charge (+), found in nucleus of an atom NEUTRON: Neutral Charge (0), found in the nucleus ELECTRON: Negative Charge (-), surrounds the nucleus ATOMS by Tim and Moby

Brain Pop: Atoms

Look at your periodic table….

Calculating Protons, Electrons, Neutrons • Atomic NUMBER = # of protons • # of protons = # of electrons • # of neutrons = Atomic MASS – # of protons • *Valence Electrons = the group number it is in Now try yourself: 1) How many protons, electrons and neutrons are in an atom of CARBON? ? 2) How many protons, electrons and neutrons are in an atom of LITHIUM? ?
