Atomic bonding

  1. 1. ATOMIC BONDING<br />Class notes<br />Thursday, Sept. 23, 2010<br />
  2. 2. Positive or negative charge?<br />An atom that GAINS one or more electrons will have a _POSITIVE______ charge<br />An atom that LOSES one or more electrons will have a __NEGATIVE__________ charge<br />
  3. 3. Ions<br />An atom that GAINS or LOSES an electron is called an __ION________.<br />A positive ion is called a _CATION_________.<br />A negative ion is called a _ANION__________.<br />
  4. 4. Ionic bonding (metal and non-metal)<br />Atoms will __TRANSFER________ one or more electrons to another to form the bond<br />Each atom is left with a _COMPLETE____outer shell<br />Forms between a __CATION_______ ion with a positive charge and an _ANION___________ ion with a negative charge<br />
  5. 5. EXAMPLES of ionic bonding<br />Sodium (Na) + chlorine (Cl)<br />Magnesium (Mg) + oxygen (O)<br />
  6. 6. Covalent bonds<br />Atoms __SHARE_______ one or more electrons with each other to form a bond<br />Each atom is left with a _COMPLETE_______ outer shell<br />A covalent bond forms between two ___NON-METALS__<br />
  7. 7. EXAMPLES of covalent bonding<br />Hydrogen (H) + hydrogen (H)<br />Hydrogen (H) + oxygen (O)<br />
  8. 8. Covalent bonds continued…<br />Carbon ( C ) + 2 oxygen (O)<br />
