Use the following key to classify each of the elements below in its elemental form: A. Discrete atoms ... C. Metallic lattice B. Molecules ... D. Extended, three-dimensional network 1. Krypton 2. Argon ... 3. Phosphorus 4. Nitrogen ...

1. Krypton Discrete atoms

2. Argon ... Discrete atoms

3. Phosphorus Molecules

4. Nitrogen Discrete atoms

Explanation:

A. Discrete atoms are those that form very weak intermolecular forces,

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

C. 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 continue display and contain the composition and chemical properties of the substance.

D. Extended structure

An element or compound that organizes or arranges themselves in a specific pattern.

1. Krypton Discrete atoms

2. Argon ... Discrete atoms

3. Phosphorus Molecules

4. Nitrogen Discrete atoms
