Key Questions:

1. How can different atoms interact with each to gain a full outer shell of electrons.
   • Atoms can gain, lose or share electrons. (Metals on their own will delocalise their outer electron(s).)
2. What are the three types of chemical bonding?
   • Ionic, Metallic and Covalent
3. Name the type of attraction between particles in an ionic bond
   • Electrostatic attraction (attraction between oppositely charged Particles)
4. In terms of electrons, how are covalent bonds formed?
   • When two non-metal atoms share electrons to form a bond
5. Metallic bonds have delocalised electrons. What are delocalised electrons?
   • Electrons in a molecule, ion or solid metal that are not associated with a single atom
6. Ionic bonding occurs in compounds formed from ________ combined with ___________.
   • Ionic bonding occurs in compounds formed from METALS combined with NON-METALS.
7. Covalent bonding occurs when _____________ atoms bond together.
   • Covalent bonding occurs when NON-METAL atoms bond together.
8. Metallic bonding occurs between atoms of __________ elements.
   • Metallic bonding occurs between atoms of METAL elements.
9. What is chemical bonding?
   • chemical bonding is where atoms are held together because of electrostatic Forces caused by the transfer or sharing of electrons.
