Chapter 2 Section 3:  Atom- smallest unit of matter that cannot be divided  Proton is a POSITIVE CHARGE  Neutron is a NEUTRAL CHARGE  Electron is a NEGATIVE CHARGE  Stable atoms same number of protons and electrons  Proton is an Element Chapter 2 Section5:  Covalent = sharing electrons Chapter 2 Section 6:  Non-Polar Covalent Bonds SHARE but EQUAL  H-H  C-H  C-C  O=0 --------- DOUBLE BOND, that is why there are 2 dashes and not only 1  Polar Covalent = SHARE but UNEQUAL  The electrons are shared, but they spend more time with the larger massed element  Example) WATER -Has 1 Oxygen and 2 Hydrogen elements…  Oxygen has 8 protons and 8 electrons  Hydrogen has 1 proton and 1 electron  Has 8 electrons… but spend more time with oxygen instead of hydrogen
