how can something like aluminum sulphide form? illustrate showing electron movement.

Answer 1

Aluminum sulphide can be formed by the reaction of aluminum and sulfur.

The reaction can be illustrated as follows:

Al + S → Al2S3

During the reaction, aluminum atoms lose three electrons each to form positively charged aluminum ions (Al3+), while sulfur atoms gain two electrons each to form negatively charged sulfide ions (S2-).

The electron movements can be shown as follows:

Aluminum (Al) atom loses 3 electrons:

Al ⟶ Al3+ + 3e-

Sulfur (S) atom gains 2 electrons:

S + 2e- ⟶ S2-

These ions then combine to form the ionic compound aluminum sulphide (Al2S3), which is composed of Al3+ and S2- ions in a 2:3 ratio.

Al3+ + 3S2- → Al2S3

This reaction can also be shown in a diagram:

In this diagram, the aluminum atom (Al) is shown losing three electrons, represented by three dots leaving the atom. The sulfur atom (S) is shown gaining two electrons, represented by two dots entering the atom. The resulting ions, Al3+ and S2-, are shown as separate ions before they combine to form aluminum sulphide (Al2S3).
