Potassium sulfide represented by the chemical formula K 2 S is a compound of potassium and sulfur that is moderately soluble in acids [1]. It is deliquescent and may spontaneously ignite in air. It is a reducing agent and an ionic compound [4]. Potassium sulfide can be prepared by first treating potassium hydroxide to excess hydrogen sulfide to form potassium hydrosulfide KHS. Further treatment of KHS with the same amount of potassium hydroxide generates potassium sulfide [9]. Potassium sulfide reacts with cobalt iii bromide to produce cobalt iii sulfide and potassium bromide [10]. Potassium sulfide reacts with dilute hydrochloric acid to produce potassium chloride and hydrogen sulfide [11].

Chapter 1 Chapter 1: The Chemical World 1. In Section 4. The astute reader may have noticed something: many of the ions that form have eight electrons in their valence shell. Either atoms gain enough electrons to have eight electrons in the valence shell and become the appropriately charged anion, or they lose the electrons in their original valence shell; the lower shell, now the valence shell, has eight electrons in it, so the atom becomes positively charged. For whatever reason, having eight electrons in a valence shell is a particularly energetically stable arrangement of electrons. The octet rule explains the favorable trend of atoms having eight electrons in their valence shell. When atoms form compounds, the octet rule is not always satisfied for all atoms at all times, but it is a very good rule of thumb for understanding the kinds of bonding arrangements that atoms can make. It is not impossible to violate the octet rule. Consider sodium: in its elemental form, it has one valence electron and is stable. The octet rule is a result of trends in energies and is useful in explaining why atoms form the ions that they do.

Lewis structures, also known as Lewis-dot diagrams, show the bonding relationship between atoms of a molecule and the lone pairs of electrons in the molecule. Lewis structures can also be useful in predicting molecular geometry in conjuntion with hybrid orbitals. A compound may have multiple resonance forms that are also all correct Lewis structures. This section will discuss the rules for writing out Lewis structures correctly. Writing out Lewis structures can be at times, tricky and somewhat difficult. A compound can have multiple Lewis Structures that contribute to the shape of the overall compound, so one Lewis structure of a compound may not necessarily be exactly what the compound looks like.
