What is the Difference Between Ionic and Binary Compounds?

🆚 Go to Comparative Table 🆚

The main difference between ionic and binary compounds lies in the nature of the chemical bonds between the atoms within the compounds. Here are the key differences:

  1. Ionic Compounds:
  • Formed from a positively charged ion (cation) and a negatively charged ion (anion).
  • Contain two charged elements, one being a metal and the other being a nonmetal.
  • Held together by ionic bonds, which result from the electrostatic attraction between opposite charged ions.
  • Generally have a crystalline structure and are brittle.
  • Conduct electricity in water or when dissolved, but not in their solid-state.
  1. Binary Molecular Compounds:
  • Composed of two different elements that are both nonmetals.
  • Held together by covalent bonds, which involve the sharing of electrons between the atoms.
  • Can take various forms, such as gases, liquids, or solids, and are not necessarily crystalline.
  • May have distinctive molecular formulas and names, unlike ionic compounds, which are often named according to their constituent ions.
  • Can conduct electricity in some cases, depending on the specific compound.

In summary, ionic compounds typically consist of metal and nonmetal ions held together by ionic bonds, while binary molecular compounds are made up of two nonmetal elements sharing electrons in a covalent bond.

Comparative Table: Ionic vs Binary Compounds

Ionic and binary compounds are two types of chemical compounds that differ in their bonding and formation. Here is a table highlighting the differences between them:

Property Ionic Compounds Binary Compounds
Definition Ionic compounds are formed when a metal and a nonmetal combine, resulting in a positively charged ion (cation) and a negatively charged ion (anion). Binary compounds are compounds formed from two different elements. They can be either ionic or covalent, depending on the nature of the elements involved.
Bonding Ionic compounds are formed by ionic bonds, which result from the transfer of one or more electrons from a metal to a nonmetal, leading to the formation of a cation and anion. Binary compounds can be formed by either ionic or covalent bonds, depending on the elements involved. Covalent compounds are formed when elements share electrons in a covalent bond to form electrically neutral molecules.
Naming In ionic compounds, the metal part of the compound is named as the element, while the nonmetallic part is named by dropping the end of the element and adding "-ide". Binary compounds can be named according to their constituent elements, depending on the type of bonding involved.
Examples Sodium chloride (NaCl), Calcium phosphide (CaP). Hydrogen chloride (HCl), Water (H2O).

Please note that binary compounds can be either ionic or covalent, depending on the elements involved. The table above highlights the differences between ionic compounds (a type of binary compound) and binary compounds in general.
