Explanation:

the correct match can as follows:

1.  helium ⇒ discrete atoms (helium is an inert gas)

2. oxygen ⇒ molecules (oxygen exists in molecular form as O2)

3 Magnesium ⇒ matalic lattice ( Magnesium is a metal FCC crystal Structure :) )

4 Aluminum⇒ covalent network (since it is situated in the middle of the group and posses amphoteric properties too)

The classification of each element in its elental form is as follows:

  • Calcium: Metallic lattice,
  • Helium: Discrete atom.
  • Sulfur: Discrete, Extended, three dimensional network.
  • Potassium: Metallic lattice.

According to the question:

  • We are required to determine the classification of each element according to the key given.

Discussion:

  • Discrete atoms are atoms that form very weak intermolecular forces,

  • Metallic lattices usually exist in metals, and the bond between metals are called metallic bonds .

  • A Molecule consists of two or more atoms that form the smallest recognisable unit into which a substance that is pure can be divided and consequently retains and contain the composition and chemical properties of the substance.

  • Extended structure: An element or compound that organizes or arranges themselves in a specific pattern.
