Ionic Bonding Of Ionic Compounds

Explanation
The formula for Magnesium Oxide is MgO.

Explanation
The correct answer is AlN, which stands for Aluminum Nitride. Aluminum Nitride is a compound composed of aluminum and nitrogen atoms. It has a chemical formula of AlN, where Al represents aluminum and N represents nitrogen. This compound is commonly used in the production of ceramics, semiconductors, and electronics due to its excellent thermal conductivity and electrical insulation properties.

Explanation
The formula for Lithium Iodide is LiI.

Explanation
The formula for Sodium Fluoride is NaF. Sodium Fluoride is formed by the combination of one sodium atom (Na) and one fluorine atom (F). The symbol Na represents sodium, which is an alkali metal, and the symbol F represents fluorine, which is a halogen. When these two elements react, they form an ionic compound with the formula NaF, where the sodium atom donates its electron to the fluorine atom, resulting in the formation of a sodium cation (Na+) and a fluoride anion (F-).

Explanation
The correct answer is BeO, which stands for Beryllium Oxide. Beryllium Oxide is a chemical compound composed of one beryllium atom and one oxygen atom. Its formula represents the ratio of atoms in the compound and is commonly used in chemistry to denote the composition of a substance. In this case, BeO indicates that Beryllium Oxide consists of one beryllium atom and one oxygen atom.

Explanation
AlCl3 is the chemical formula for Aluminum Chloride. It is a compound composed of aluminum and chlorine atoms. Aluminum Chloride is commonly used as a catalyst in various chemical reactions, such as in the production of polymers. It is a white, crystalline solid that is highly soluble in water. Aluminum Chloride has several applications in industries, including pharmaceuticals, dyes, and petroleum refining.

Explanation
Mg3N2 is the chemical formula for Magnesium Nitride. Magnesium Nitride is a compound formed by the combination of Magnesium (Mg) and Nitrogen (N). The subscript 3 indicates that there are three magnesium atoms, and the subscript 2 indicates that there are two nitrogen atoms present in the compound. Therefore, the correct name for the compound Mg3N2 is Magnesium Nitride.

Explanation
The name of the compound CaO is Calcium Oxide.

Explanation
The compound HI is named hydrogen iodide. This is because it consists of one hydrogen atom (H) and one iodine atom (I). In chemical nomenclature, the name of a binary compound like this is determined by combining the names of the elements present, with the name of the cation (hydrogen) followed by the name of the anion (iodide). Therefore, the correct name for the compound HI is hydrogen iodide.

Explanation
Nickel (II) oxide is the correct name for the compound NiO. In this compound, the element nickel has a +2 charge, which is indicated by the Roman numeral II in parentheses. The oxide ion has a -2 charge, so the compound is formed by the combination of one nickel ion and one oxide ion. Therefore, the correct name for this compound is Nickel (II) oxide.

Explanation
The name of the compound NaBr is Sodium Bromide. This is because Na represents the element sodium and Br represents the element bromine. When these two elements combine, they form a compound called sodium bromide.

Explanation
The name of the compound KCl is Potassium Chloride. KCl is formed by the combination of the elements potassium (K) and chlorine (Cl). In chemical nomenclature, the name of an ionic compound is determined by the cation (in this case, potassium) followed by the anion (chloride). Therefore, the correct name for KCl is Potassium Chloride.

Explanation
Mercury Oxide is represented by the chemical formula HgO. This formula indicates that the compound is composed of one mercury (Hg) atom and one oxygen (O) atom. The symbol "Hg" represents the element mercury, while "O" represents oxygen. The subscript "1" is not explicitly written, as it is understood that there is only one atom of each element in the compound. Therefore, the formula HgO accurately represents the composition of Mercury Oxide.

Explanation
The correct answer is LiH, which represents lithium hydride. Lithium hydroxide, on the other hand, is represented by the formula LiOH. Therefore, the given answer is incorrect.
