Stable Atom
cloud
Reactive Atom
atomic mass =
charge of electrons
valence electrons
charge proton
charge of neutron
nucleus
center of an atom, contains protons and neutrons
happy atom! Has a full valence shell (8ve-)
protons + neutrons
area surround the nucleus
electrons farthest from the nucleus, responsible for reactivity/bonding
no charge, 0
positive +
sad atom, doesn't have a full valence shell (less then 8) so it wants to bond with others
negative -
