These salts have ionic bonds.
Salts do not usually contain covalent bonds e.g. NaCl doesn't.
RbCl because Rb has more valence electrons
Sodium chloride has an ionic bond.
NH3 contains covalent bond
NaCl is a type of ionic bond. because it formed by the Na+ and Cl- ions formed in the process of ionization.
Ionic bonds in compounds such as NaCl and covalent bonds in say diamond (C) and quartz (SiO2)
ionic: NaCl, KCl, KOH etc covalent: H2, O2, CH4 etc
MgF2 and NaCl are ionic. NH3 and H2O contain polar covalent bonds. N2 contains non polar covalent bond.
Ionic bond between Rb+ cation and Cl- anion.
Ionic bonds are between a metal and a nonmetal. Covalent bonds are between a non-metal and a non-metal. Na (metal) + Cl (non-metal) = ionic Cl (non-metal) + Cl (nonmetal) = covalent
Ionic bonds, Covalent bonds, Hydrogen bonds, Polar Covalent bonds, Non-Polar Covalent bonds, and Metallic bonds.
