Ionic Bonds Ionic Bonds- is a type of chemical bond that involves a metal and a nonmetal ion through electrostatic attraction. In short, it is a bond formed by the attraction between two oppositely charged ions.
Why do bonds form? Whenever a bond is formed there is a release of energy as it becomes more stable Stable = good = energy Whenever a bond is broken there is a absorption of energy as it becomes less stable Not stable = bad = loss of energy http://upload.wikimedia.org/wikipedia/commons/7/75 /Ionic_bonding_animation.gif http://upload.wikimedia.org/wikipedia/commons/7/75 /Ionic_bonding_animation.gif
Valence Electrons Valence electrons: are the electrons that are found in the outer most electron shell or energy level of a atom. Valence electrons can be found on your periodic table of elements.
Gilbert Lewis Gilbert Lewis was an American physical scientist that is credited for the Lewis dot diagrams Lewis also coined the term Full Octet of electrons stating that all atoms want to have a full outer most energy level
Ionic Bonds For an ionic bond to from the less electronegative atom (the metal) will transfer its valence electron or electrons to a more electronegative atom (the nonmetal) ex NaClMgS
With your partner draw out the Lewis dot diagrams following Be 2+ K 1+ Cl 1- O 2- MgSLiClBeF 2
