chemical bonds

• What is the primary way atoms combine with each other?

  Through the movement of electrons
• Why do atoms combine with other atoms?

  To achieve a greater level of stability
• What is achieved when an atom obtains a full outer shell of electrons?

  A greater level of stability
• What are the three types of bonding studied at GCSE?

  • Ionic bonding
  • Covalent bonding
  • Metallic bonding
• What occurs during ionic bonding?

  Metals and non-metals react by transferring electrons
• What are the particles involved in ionic bonds called?

  Ions
• How do opposite charges behave in ionic bonding?

  They attract through electrostatic forces
• What is the nature of covalent bonds?

  Non-metal atoms share pairs of electrons
• In which materials does metallic bonding occur?

  In metals and metal alloys
• What are the key characteristics of ionic, covalent, and metallic bonding?

  • Ionic bonding: Transfer of electrons between metals and non-metals, forming oppositely charged ions.
  • Covalent bonding: Sharing of electron pairs between non-metal atoms.
  • Metallic bonding: Occurs in metals and metal alloys, involving a sea of delocalized electrons.
• ionic bonding


  occurs with compounds of metals and non metals
• covalent bonding


  non metal atoms share pairs of electrons between eachother
• metallic bonding


  • This type of bonding occurs in metals and metal alloys (mixtures of metals)
• Chemical Bonding

  Cohesion between atoms caused by electrostatic forces and sharing/transfer of electrons.
• Ionic Bonding


  Transfer of electrons between atoms, resulting in oppositely charged ions.
• Covalent Bonding


  Sharing of electrons between atoms with similar electronegativity.
• Metallic Bonding


  Delocalization of electrons, allowing for free movement throughout the metal.
