Answer:
Potassium nitrate
Explanation:
Because NO3 (nitrate) consists of 4 covalently bonds atom. NO3, incorporate of nitrate which share electrons then Ionic bonding occurred between K(as cation) NO3(as anion).
Answer: 3) potassium nitrate
Explanation:
An ionic bond is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element and forms a positively charged ion called as cation. The element which accepts the electrons is known as electronegative element and forms a negatively charged ion called as anion.
A covalent bond is formed when an element shares its valence electron with another element. This bond is formed between two non metals.
1. potassium chloride :[tex]KCl[/tex] is made up of ionic bond between metal and non metal.
2. potassium hydride :[tex]KH[/tex] is made up of ionic bond between metal and non metal.
3) potassium nitrate : [tex]KNO_3[/tex] made up of ionic bond and [tex]NO_3[/tex] is made up of covalent bond between two non metals nitrogen and oxygen.
4) potassium oxide: [tex]K_2O[/tex] is made up of ionic bond between metal and non metal.
Thus potassium nitrate contains both ionic and covalent bonds.
