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