is KNO3 a Covalent or Ionic bond?

3 Answers

  • Potassium nitrate, KNO3, is often called an “ionic compound”. KNO3 is a network solid consisting of alternating potassium atoms and nitrate radicals. The bonds between K and O are highly polar making them high in ionic character, yet the bonds between N and O have high covalent character.

  • You’d rarely see covalent bonds in a compound that contains alkali metals. Since K is an alkali metal (group (column) #1), it’s ionic bonding. You can figure it out too since K has +1 charge and NO_3 has a -1 charge (they’re both IONS).

  • The NO3 part is covalently bonded, as electrons are shared between N and O.
