Question

What is a binary chemical compound? What are the two major types of binary chemical compounds? Give three examples of each type of binary compound.

Short answer

A binary chemical compound is a compound formed by the combination of two different elements, which can be categorized into two major types: ionic and covalent. Ionic compounds are formed by the electrostatic force of attraction between oppositely charged ions, usually formed from a metal and a nonmetal element, such as sodium chloride (\(NaCl\)), magnesium oxide (\(MgO\)), and calcium fluoride (\(CaF_2\)). Covalent compounds are formed when atoms share electrons to achieve a stable electron configuration, usually formed between nonmetal elements, such as hydrogen chloride (\(HCl\)), water (\(H_2O\)), and carbon dioxide (\(CO_2\)).

Step-by-step solution

Definition of Binary Chemical Compound

A binary chemical compound is a compound formed by the combination of two different elements. These compounds can be categorized into two major types: ionic and covalent.

Types of Binary Chemical Compounds

The two major types of binary chemical compounds are: 1. Ionic Compounds: These are compounds formed by the electrostatic force of attraction between oppositely charged ions, usually formed from a metal and a nonmetal element. 2. Covalent Compounds: These are compounds formed when atoms share electrons to achieve a stable electron configuration, usually formed between nonmetal elements.

Ionic Binary Compounds: Examples

Here are three examples of ionic binary compounds: 1. Sodium chloride (\(NaCl\)): Sodium chloride is formed by the electrostatic force of attraction between a positively charged sodium ion (\(Na^{+}\)) and a negatively charged chloride ion (\(Cl^{-}\)). 2. Magnesium oxide (\(MgO\)): Magnesium oxide is formed by the electrostatic force of attraction between a positively charged magnesium ion (\(Mg^{2+}\)) and a negatively charged oxide ion (\(O^{2-}\)). 3. Calcium fluoride (\(CaF_2\)): Calcium fluoride is formed by the electrostatic force of attraction between a positively charged calcium ion (\(Ca^{2+}\)) and two negatively charged fluoride ions (\(F^{-}\)).

Covalent Binary Compounds: Examples

Here are three examples of covalent binary compounds: 1. Hydrogen chloride (\(HCl\)): Hydrogen chloride is formed when a hydrogen atom shares an electron with a chlorine atom to create a single covalent bond. 2. Water (\(H_2O\)): Water is formed when two hydrogen atoms each share an electron with an oxygen atom, creating two single covalent bonds. 3. Carbon dioxide (\(CO_2\)): Carbon dioxide is formed when a carbon atom shares two electrons with each oxygen atom, creating two double covalent bonds.
