The particles that makeup lattices of the Van Der Walls crystals, ionic crystals and covalent crystals are respectively Correct Answer molecules, ions, atoms

Concept:

The crystal lattice is known as regular arrangements of constituent particles such as atoms, ions or molecules of a crystalline solid in 3-D space.

Van Der Waals Crystal / Molecular Crystal.

  • A solid which consist of a lattice array of molecules such as hydrogen, methane or more organic compounds bound by Van Der Waals forces or hydrogen bonds is known as Van Der Waals Crystal.
  • General properties of the Van der Waals crystal are soft, low melting point, a poor conductor of heat and electricity. 

Ionic crystals.

  • Lattice points which occupied by charged particles (ions) and are held together by columbic forces. 
  • Size and the relative number of each ion determine the crystal structure. 

Covalent Crystals. 

  • Lattice points are occupied by the neutral atoms. In which atoms are held together by covalent bonds. 
  • These crystals are hard solid and poor conductors of electricity. 

Explanation:

  • Molecules make up the lattices of Van der Waals crystals, 
  • Ions make up the lattices of ionic crystals
  • Atoms make up the lattices of covalent crystals. 

So, The particles that make up lattices of the Van Der Walls crystals, ionic crystals and covalent crystals are respectively molecules, ions, atoms.
