C2 Chemical Bonding

<ul><li>Ionic Bonding</li><li>Covalent Bonding</li><li>Metallic Bonding</li></ul>

<p>Ionic Bonding is bonding between two oppositely charged ions</p>

<p>Ionic Bonding is found in compounds made of metals and non-metals</p>

<p>Covalent bonding is the bonding of two atoms sharing 1 or more pairs of electrons</p>

<p>Covelant bonding is found in most non-metal elemnts and in compounds of non-metals</p>

<p>Metallic Bonding is the attraction between positively charged ions and negatively charged delocalised electrons</p>

<p>Metallic Bonding is found in metals and alloys</p>

<p>Ions are charged particles</p>

<p>Positively charged ions are formed when an atom or molecue loses electrons</p>

<p>Cations</p>

<p>Negatively charged ions are formed when an atom or molecule gains electrons</p>

<p>Anions</p>

<p>Ionic Lattices are giant structures held together by strong electrostatic forces between oppositely charged ions</p>

<p>Melting is when a solid is heated to its melting point and changes into a liquid</p>

<p>Boiling is when a liquid is heated to its boiling point and evaporates into a gas</p>

<p>Condensing is when a gas is cooled to its boiling point and turns into a liquid</p>

<p>Freezing is when a liquid is cooled to melting point and turns into a solid</p>

<p>Some substances have high melting points as there are strong intermolecular forces between the particles</p> <p>This means a lot of energy is required to melt the solid</p>

<p>Sublimation is a process that changes a solid to a gas</p>

<p>Desublimation or Deposition is a process that changes a gas to a solid</p>

<p>Ionic Compounds always form Giant Ionic Lattice Structures</p>

<ul><li>High Melting and Boiling Points</li><li>Conducts electricity when molten or dissolved</li></ul>

<p>The Ions in the lattice are free move so charge can flow</p>
