Bonding and Structure.’ ⚛️

• What is a compound?

  A substance made of two or more elements
• What is an element?


  A substance made up of only one type of atom
• What is a mixture?


  A combination of two or more different types of molecules
• What do Chemical bonds do?

  Bond atoms together to form molecules
• What are the two parts of a solution?

  Solute and solvent
• What is an aqueous solution?

  A solution in which water is the solvent.
• How do you make a solute dissolve more quickly?

  heat up or stir the solvent
• What does it mean if a solution is concentrated? if it has a high amount of solute dissolved in a given amount of solvent.
• What does it mean if a solution is diluted?

  Less concentrated
• Give an example of a solution


  Sea water,

  Water= solvent

  Salt= Solute
• What does it mean if a solution is insoluble? Give an example


  When it cannot dissolve in water, for example sand
• What is an alloy?


  A mixture of two or more metals.
• What is Ionic bonding?


  Bonding between a metal and a non metal
• What is Bonding between two metals called?


  Metallic bonding
• What is bonding between two non metals known as?


  Covalent bond
• What is filtration?


  Separation of solid particles from a liquid
• What term refers to the liquid at the bottom of the conical flask in filtration?


  Filtrate
• What is the term that refers to the insoluble solid collected by the filter paper?


  Residue
• What is distilation?


  Separation of components in a liquid mixture based on differences in boiling points.
• What is the name given to the structure of an Ionic or Metallic compound?

  Lattice
• What does a lattice look like?

  A giant cube of atoms

  
• What makes a pure substance?

  Just one type of element or compound
• What makes a mixture?

  Two or more elements or compounds
• a=mixture

  b=mixture

  c=pure

  d=mixture

  e=mixture

• What happens to some solutions when they get more concentrated?

  They get darker e.g Ribena in water
• How might you tell if a colourless substance is a solution?

  Measure the volume, and the mass, if the mass is greater then it is a solution
