FREE Expert Solution

We’re asked to classify each substance as an atomic element, a molecular element, an ionic compound, or a molecular compound based on the following molecular views.


Recall that:

  • atomic element - an element that exists by itself in nature
  • molecular element - an element that exists as molecules containing 2 or more of the same elements  bonded together (e.g. diatomic molecules)
  • ionic compound - a compound consisting of elements bonded together in an ionic bond (metal + nonmetal)
  • molecular compound - a compound consisting of elements bonded together in a covalent bond (nonmetal + nonmetal)

Problem Details

Based on the following molecular views, classify each substance as an atomic element, a molecular element, an ionic compound, or a molecular compound.Three molecular views: a, b, and c. View a is a collection of six pairs of white spheres, each pair comprised of two white spheres combined, with the pairs relatively far apart. View b is a collection of three molecules, each consisting of a central blue sphere surrounded by three smaller white spheres, each molecule is relatively far apart. View c is a collection of purple spheres packed closely together in an ordered, repeating arrangement.
