bonding and structure

• Conductor is a material that contains charged particles which are free to move and carry electric or thermal charge
• Covalent bond is a shared pair of electrons between two non metals
• Diamond is a giant covalent structure that is made or carbon atoms each of which form four covalent bonds with four other carbon atoms
• Electrostatic forces are the strong forces between oppositely charged ions
• Fullerenes are molecules or carbon atoms with hollow shapes and they are based on hexagonal rings or carbon atoms
• Graphing is a single layer of graphite
• Graphite is a giant covalent structure that binds with 3 other carbon atoms forming hexagonal rings which have no covalent bonds between the layers
• An ion is a charged particle that has gained or lost electrons.
• Ionic compound is a chemical compound formed of ions and held together by electrostatic forces
• Intermolecular forces are the forces that exist between molecules
• A lattice is a repeating arrangement or atoms or ions or molecules
• Metallic bond is a bond between positive metal ions and delocalised electrons
• Ionic compounds Contain oppositely charged ions that are attracted to each other.
• Covalent compounds occur in particles that share pairs of electrons
• Metallic compounds have particles that share de localised electrons and are arranged in a regular lattice structure
• In ionic compounds the force is in every direction
• Ionic compounds are help together by strong electrostatic forces of attraction between oppositely charged ions
• polymers are large covalently bonded structures
• You can use ball and stick diagram to represent covalent bonds
• in metallic bonding the delocalised electrons more freely throughout the structure
• Metallic bonds are very strong
• The layers or atoms in metals allow metals to be bent and shaped
• Metals are good conductors
• Alloys are harder than pure metals
• Ionic compounds can conduct electricity when melted or dissolved
• graphene is elastic because the planes or atoms can flex relatively easily
• when a metal reacts with a non metal this is ionic bonding
• in ionic bonding both atoms achieve full outer shells
• giant ionic lattices have very strong electrostatic forces of attraction between ions
• ionic compound have very high melting and boiling points as they are made up of strong electrostatic forces
• ionic compound can conduct electricity when melted or dissolved because the ions are free to move
• covalent bonding takes place in non metal elements
• a covalent bond is a shared pair of electrons
• small covalent bonds have low melting and boiling points and are liquids and gases at room temp
• covalent structures have weak intermolecular forces holding them together
• small covalent molecules dont conduct electricity because the molecules dont have an overall charge
• three types of strong chemical bonds

  ionic , covalent , metallic
• ionic bonding is between oppositely charges ions
• what is ionic bonding

  bonds between oppositely charged ions
• covalent bonds are between particles which share a pair of electrons
