Metallic bonds form between metal cations and delocalized electrons, allowing metals to conduct electricity. Organic compounds contain carbon and form covalent bonds, while inorganic compounds lack carbon and usually form ionic bonds between metals and nonmetals. Ionic bonds occur when atoms transfer electrons, and covalent bonds form when nonmetals share electrons equally. Electronegativity determines whether atoms form ionic or covalent bonds based on their ability to attract bonding electron pairs.

1. Metallic Bonds & Others

2. Metallic Bond Metallic Bond = Metal bonds An attraction between metal cation (+ charge proton) and the shared electrons that surround it. Metals share electrons (pass along = Current) Metals atoms shift and move within their structure

3. Organic & Inorganic Organic = Compound made with carbon that are covalent bonded Sugar / Protein / DNA / Fat Inorganic = Compounds without carbon mostly ionic bonded Salts / Crystals / Minerals

4. Ionic bond Ionic bond = bond between a metal and non-metal Charged atoms result Easier to gain one or two electrons than to give up 6 or 7 electrons

5. Covalent bond Covalent bond = A bond between two non-metals Electrons get Shared part of the time… Each element thinks it has 8 electrons all the time Easier to share 4 electrons than to try to give them up or take from other elements

6. Electronegativity Electronegativity = is a measure of the tendency of an atom to attract a bonding pair of electrons

7. Electronegativity The more negative element will hold electrons closer & tighter Indicate type of bond Ionic or Covalent
