NaCl is ionic, but it is not a molecule. Molecules can only be covalent.
so they cant disolve
The cation,Na +and the anion,Cl -form the ionically bondedNaClsodium chloride.
covalent
Depends on the compound; chlorine can form an ionic bond with many elements. eg, NaCl, MgCl2, CsCl.
Calcium oxide is an ionically bonded compound that contains equal numbers of calcium cations with a charge of +2 and oxide anions with a charge of -2.
Elements from Group 1 (such as sodium) and Group 2 (such as magnesium) would bond ionically with chlorine. Sodium would form NaCl (sodium chloride) and magnesium would form MgCl2 (magnesium chloride) through ionic bonds with chlorine.
Potassium sulfate contains both covalent and ionic bonding. Potassium cations are bonded ionically to the polyatomic sulfate anions, and these anions are internally bonded covalently.
CO. NaCl is not a molecular compound, because it is ionically bonded.
Freon is more covalently bonded. It consists of covalent bonds between the carbon, fluorine, and chlorine atoms in its structure.
Water molecules bond covalently, where the oxygen atom shares electrons with the two hydrogen atoms to form a stable molecule. The interaction between water molecules, known as hydrogen bonding, is a weak form of intermolecular bonding that is responsible for many of water's unique properties.
Calcium is a metal with an electronegativity of 1.0 and oxygen is a nonmetal with an electronegativity of 3.5. The electronegativity difference is 2.5, and anything over 1.7 indicates an IONIC BOND.
The same atoms bonded together are elements. Different atoms bonded together are compounds. Oxygen gas, O2, is an element composed of molecules of two oxygen atoms covalently bonded. Water, H2O is a molecular compound composed of two hydrogen and one oxygen atoms covalently bonded. Common table salt, NaCl, is an ionic compound composed of sodium and chloride ions ionically bonded.
