Chemical Bonds

• What are the three types of strong chemical bonds?


  Ionic, covalent, metallic
• How does ionic bonding occur in terms of particles ?


  For ionic bonding, the particles are oppositely charged ions
• How does covalent bonding occur in terms of particles?


  The particles are atoms which share pairs of electrons
• How does metallic bonding occur in terms of particles?


  For metallic bonding the particles are atoms which share delocalised electrons
• Where does ionic bonding occur?


  Between metals and nonmetals.
• Where does covalent bonding occur?


  Between nonmetals.
• Where does metallic bonding occur?


  Metals
• How does electrostatic forces form chemical bonds?


  The electrostatic attraction between the positively charged nuclei of the atoms and the negatively charged electrons
• How does ionic bonding occur in terms of electrons?


  In ionic bonding, there is a transfer of electrons usually from the metal atom losing electrons for the nonmetal atom to gain forming an ionic bond due to the electrostatic attraction between the opposite charges
• How does covalent bonding form in terms of electrons?


  In covalent bonding, there is sharing of electrons between nonmetals to form a full outer shell
• How does metallic bonding occur in terms of electrons?


  • In metallic bonding, metal atoms release some of their electrons, creating a "sea of delocalised electrons" that are free to move around.
  • This results in a strong electrostatic attraction between the positively charged metal ions and the delocalized electrons, giving metals their characteristic properties like conductivity and malleability.
