Which of the following compounds results from the formation of an ionic bond?
A.
H2O
B.
NO2
C.
NaCl
D.
CO2
C. NaCl
The compound that results from the formation of an ionic bond is C. NaCl.
To determine which of the listed compounds results from the formation of an ionic bond, we need to understand what an ionic bond is and examine the properties of each compound.
An ionic bond is a type of chemical bond that occurs between a metal and a non-metal. In this bond, one atom transfers electrons to another atom, resulting in the formation of positive and negative ions. The electrostatic attraction between these ions holds the bond together.
Let's evaluate each compound:
A. H2O (water): Water is a covalent compound. It consists of two hydrogen atoms bonded covalently to an oxygen atom. Covalent bonds occur when atoms share electrons, rather than transferring them.
B. NO2 (nitrogen dioxide): Nitrogen dioxide is also a covalent compound. It consists of a nitrogen atom bonded covalently to two oxygen atoms.
C. NaCl (sodium chloride): Sodium chloride is an ionic compound. It is formed by the transfer of electrons from sodium (a metal) to chlorine (a non-metal). Sodium donates one electron to chlorine, resulting in the formation of a positively charged sodium ion (Na+) and a negatively charged chloride ion (Cl-). The electrostatic attraction between these ions forms the ionic bond.
D. CO2 (carbon dioxide): Carbon dioxide is another covalent compound. It consists of one carbon atom bonded covalently to two oxygen atoms.
Based on this information, the compound that results from the formation of an ionic bond is C. NaCl (sodium chloride).
