Which formula represents an ionic compound?
(1) NaCl (3) HCl
(2) N2O (4) H2O

Sagot :

NaCl consists of a salt, which is a nonmetal (Na) and Cl, which is a metal. When a nonmetal and a metal are combined, it makes the compound ionic.

Answer is: 1) NaCl.

NaCl is sodium chloride, ionic compound.

Ionic compounds are made of ions held together with ionic bonds.  

Ionic bond forms when a cation transfers its extra electron to an anion who needs it.  

Electronegativity (χ) is a property that describes the tendency of an atom to attract a shared pair of electrons.  

Δχ(Na-Cl) = 3.2 - 0.95 = 2.25; electronegativity difference between sodium and chlorine.

When the electronegativity difference is greater, the bond polarity is increasing.

Other compound have covalent polar bonds.
