Barium Sulfide: Understanding the Lewis Structure and Atom Information

Have you ever heard about barium sulfide? It may sound unfamiliar to you, but it is a compound used in various applications such as photography, electronic and chemical industries.

Understanding its structure and properties is essential to explore its numerous benefits. This article will delve deeper into the various aspects of barium sulfide to help you appreciate its role in different areas.

Barium Sulfide Lewis Structure

The Lewis concept is an essential tool in understanding the bonding between metal and non-metal elements. Barium sulfide is an ionic compound, meaning that one metal element, barium, is combined with a non-metal element, sulfur.

The valence electrons, which are the outermost electrons of an atom that determine its bonding behavior, play an important role in determining the Lewis structure of barium sulfide. If we consider the electron configuration of each element, barium (Ba) has two valence electrons while sulfur (S) has six valence electrons.

To obtain the complete octet, barium gives two electrons to sulfur, forming an ionic bond, and each atom obtains the stable noble gas electron configuration. The Lewis structure of BaS can be represented by a pair of dots (or minus sign) next to S, indicating that two electrons were received, along with the cation of Ba.

Resonance in Lewis Structure

The molecule of barium sulfide is octahedral, meaning that it has a central barium atom surrounded by six sulfur atoms. When there is more than one plausible structural formula for a molecule, it is referred to as resonance.

In the case of BaS, there is only one plausible structure. The electrons are delocalized among sulfur atoms, and the molecule has no double bonds.

Formal Charge Calculation

The formal charge is a measure of the difference between the number of valence electrons in a free atom and the number of electrons assigned to it in a compound. The formal charge can be calculated using the formula Formal Charge= Valence Electrons- Non-bonded Electrons- 1/2 Bonded Electrons.

In the Lewis structure of BaS, the sulfur atom has two bonds and has four valence electrons. Therefore, the formal charge of sulfur is -1, while barium has a formal charge of +2.

Bond Angle and Octet Rule

The octet rule is a simple yet important rule that describes how atoms tend to combine to attain a stable electron configuration. Atoms tend to gain, lose or share electrons to fill their outermost shell with eight electrons, which is known as a stable octet.

In BaS, both barium and sulfur have stable octets since barium has lost two electrons to sulfur, and sulfur now has an octet of electrons. The bond angle between the sulfur atoms in the BaS molecule is 90 degrees, and between barium and sulfur, it is 180 degrees.

Lone Pairs and Valence Electrons

The octahedral geometry of BaS increases the contribution of valence electrons and lone pairs in predicting its molecular structure. VSEPR theory (Valence Shell Electron Pair Repulsion) can help predict the molecular structure of BaS, where the charge density on the central atom, barium, repels the surrounding sulfur atoms.

The octahedral arrangement of the sulfur atom creates a possibility of lone pairs, which can affect the molecular structure of the compound by creating distortions in the electron clouds around the atoms.

Hybridization

Hybridization is the process of mixing atomic orbitals to form new orbitals with different properties from the parent orbitals. In this case, the hybridization is sp hybridization, where one 3s and two 3p orbitals mix to form three new hybrid orbitals, one of which is used in bonding.

Hybridization explains how BaS can form an ionic bond despite being a metal-nonmetal combination. The energy required to form hybrid orbitals is much lower than what would be required to promote an electron from a stereochemically inert s orbital to a stereochemically active p orbital.

Solubility, Ionic and Polar/NP

Solubility of BaS in different solvents is vital for its applications. BaS is insoluble in water but soluble in polar solvents such as methanol and ethanol.

This is due to its ionic nature, where it dissociates in polar solvents forming Ba2+ and S2- ions, which are highly attracted to the polar solvent molecules due to their different electronegativities. On the other hand, BaS is not soluble in non-polar solvents due to the lack of any interaction between its ionic bonds and the nonpolar solvent.

Barium and Sulfur Atom Information

For barium, its atom has atomic number 56, and its electron configuration is [Xe]6s2. The valence electrons of barium are in the outermost 6 s orbital.

For sulfur, its atom has atomic number 16, and its electron configuration is [Ne]3s2,3p4. In sulfur, the valence electrons are found in the outermost 3s and 3p orbitals.

Conclusion

In conclusion, understanding barium sulfide’s structure and properties is key to knowing its applications in different industries. From its Lewis structure, resonance, and formal charge to bond angles, hybridization, and solubility, barium sulfide’s unique properties with respect to its atoms are an important aspect to appreciate to unlock its chemical potential.
