Worksheet: Types of Solid

In this worksheet, we will practice identifying simple molecular, giant covalent, ionic, and metallic materials and comparing their physical properties.

Q1:

Which of the following is not a solution?

  • ABrine
  • BSteel
  • CSaline
  • DIron
  • ESyrup

Q2:

Which one of the following is true for solids?

  • ASolids cannot be compressed.
  • BAll solids are made of atoms in a regular lattice.
  • CSolids are made of only one type of atom.
  • DSolids keep their shape without a container to support them.
  • ESolids can only be mixed with other solids.

Q3:

Which of the following is true for liquids?

  • AWhen a solid melts, the liquid formed has less energy than the solid did.
  • BThe particles in a liquid do not move, but vibrate really fast.
  • CA liquid can condense to form a gas.
  • DThe particles in a liquid are free to move around each other, making it flow and take the shape of its container.
  • EAll materials can form a liquid.

Q4:

Which of the following is true for gases?

  • AGases are much denser than liquids or solids.
  • BAtoms in a gas always bond to form diatomic molecules.
  • CAll reactions produce some form of gas as a by-product.
  • DGases expand spontaneously to occupy the maximum available space.
  • EGases condense above a critical temperature.
