The Periodic Table
*******A group tells you how many valence electrons the element has.
Period - a horizontal row in the periodic table (sideways)
*******A period tells you how many orbitals the element has.
Determining P, E, N.
*electrons = the atomic number
*neutrons = the atomic mass rounded minus the atomic number
Valence Electons ---- Look up at the picture above again!
*determine how the atoms bond
**To find the number of valence electrons, look at the group number of the element.
