3 FORCES What is a chemical bond? The force that holds two atoms together
4 Between different molecules Forces Within a compound (between elements) Intermolecular Forces Intramolecular Forces STRONGER Occurs in proteins When H bonds to N, O, F Nonmetal-Nonmetal Sharing of Metals Surrounding sea of Metal-Nonmetal Gain or loss of Unequal sharing of Equal sharing of
5 Intramolecular Force (stronger) holds elements together to make compounds Intermolecular Force (weaker) holds molecules together to form solids, liquids, and gases
6 Intramolecular Force The force within a compound between atoms. Example: the bond between O and H in a H 2 O molecule

13 Ion- charged elements When an atom loses a valence electron to another atom, it becomes a (+) ion. This is a CA+ION. When an atom accepts a valence electron from another atom, it becomes a (-) ion. This is an ANION.

29 Between different molecules Forces Within a compound (between elements) Intermolecular Forces Intramolecular Forces STRONGER Occurs in proteins When H bonds to N, O, F Nonmetal-Nonmetal Sharing of Metals Surrounding sea of Metal-Nonmetal Gain or loss of Ionic Bond STRONGEST Covalent Bond Metallic Bond Unequal sharing of Polar Nonpolar Equal sharing of
30 Polar Covalent Bond are unevenly shared; different EN values Nonpolar Covalent Bond are evenly shared; same or very close EN values
31 Electronegativity is the tendency of an atom to attract other atoms valence The more electronegative the atom, the stronger the attraction for Fluorine is the most electronegative atom on the periodic table
32 Fluorine the Flirt likes to attract other atoms valence Examples: H-F (polar) H-H (nonpolar)
33 The O atom pulls on the shared in each H causing a partial (+) charge on each H atom and partial ( ) charge on the O atom Why is O pulling the towards itself? O is more electronegative and attracts the unequal sharing of Why does water act like a magnet? Because the (+) attracts the (-)
34 Free floating among metals
35 Intermolecular Force The force between different molecules Example: an interstate highway runs between different states
36 Intramolecular Force Intermolecular Force
37 Intermolecular Force Intramolecular Force

43 Why do atoms form chemical bonds? How? To become more stable by losing, gaining, or sharing What does it mean when an atom is chemically unstable? It does not have a full octet of What does the octet rule state? The outermost energy level has 8 valence (full shell) What subatomic particle is involved in forming chemical bonds? Valence What is a molecule? Two or more elements chemically combined together How can the periodic table be used to determine the # of valence? Look at the group number (Transition Metals are different) How can the periodic table be used to determine the # of energy levels? Look at the period number Most matter is electrically neutral, why?
