Chemical bonding Powerpoint

  1. 1. Chemical Bonding Vy Bui, Lalein A. Pajarillo
  2. 2. IntroductionChemical Bond – the type of force that holds two or more atoms together. It is the attraction between positive nucleus and their negative electrons.There are 3 types of bonds… Ionic Bond Metallic Bond Covalent Bond
  3. 3. Ionic BondingThis is the reaction between a metal (cation) and non-metal (anion) where in the cation transfers its valenceelectrons to the anion due to electrostatic force inorder to make it stable (octet rule). Strong bonding.Its properties: Hard High melting boiling point Brittle
  4. 4. Ionic Bonding (Potassium) (Bromine) Now, Br K + Br K+ + Br - gained an electron making it a negative ion. It also achieve K transfer its the octet rule. electron to the Br Thus they, formed the KBr or the becoming a Potassium Bromide. positive ion.Other Examples:
  5. 5. Metallic BondingThe kind of bonding between metallic elements in whichthe valence electrons can move freely from one atom toanother. Since they can move freely they are calleddelocalized electrons. They do not share, lose or gainelectrons. Their valence electrons form a "sea” of electrons.Weak bonding.Properties: High melting and boiling points Electrical and heat conductorExamples of metal elements: Lithium, Magnesium, Sodiumetc.
  6. 6. Covalent BondingCovalent bonding is the result of chemical bonding of elementsthat share pairs of valence electrons. These bond are usuallyformed between non-metal elements.Three types of Covalent Bonds… Single Bond: A single covalent bond is formed when two atoms bond and share a single pair of electron. Double Bonds: A type of covalent bond in which two electron pairs are shared between two atoms. Each atom contributes two electrons to the bond. Triple Bonds: A covalent bond in which three electron pairs are shared between two atoms. (their valence electrons are associated with how many pairs they can create)

  9. 9. Sigma Vs. PiSigma (σ) bonds are the strongest Pi(π) bonds, on the other hand, aretype of bonds in the covalent weaker bonds and they are formedbonding. They are formed by head- when parallel orbitals overlapped to share the electrons.on overlapping between atomicorbitals. The valence atomic orbitalsof the two atoms which share theelectrons overlap or merge end toend.
  10. 10. ConclusionWe therefore conclude that there are three types ofChemical bond which are Ionic, Metallic andCovalent. Each type of bonds has its ownapplicability. Ionic transfer of electrons between non-metal and metal. Metallic is the bond between metalelements in which electrons are delocalized, whilecovalent is the sharing of pairs of electrons.
