cucl is more covalent than nacl because cu has same size as that of na & cucl has pseudonobal gas configration due to which it has 18 electrons in outermost shell than na cl which has 8 elctrons
By stronger, I am guessing you meant " stronger intermolecular forces ". Ionic compounds do not necessarily have stronger intermolecular forces than covalent compounds. For example, it is true that NaCl(an ionic compound) has strong electrostatic attractions while H2O(a covalent compound) has very weak London forces. However, SiO2 is a giant covalent compound, and has very strong covalent bonds between molecules, even stronger than the electrostatic forces of NaCl.
In Sodium Chloride, Sodium ion (Na+) and Chloride ion (Cl-) are combined by ionic forces,Where as in Iodine Molecule Two Iodine atoms are combined by covalent bond.Covalent bond is always stronger than ionic Bond.So in water the weak bond (Ionic Bond) dissociates easily and Nacl Dissolves Readily compared to Iodine.
Nucleic acids would be one example of a covalent compound with more than 3 elements. Proteins have more than 3 elements as well. Many organic compounds do, it is quite common.
Calcium Carbonate. Simple test, NaCl Dissociates in water, CaCO3 does not
Much more electronegative than Sodium(Na).
It is a small difference between the electronegativity of lithium (o,98) and sodium (0,93) - for Li the value is higher.
Ionic bonds have stronger bonds than covalent but are easier to separate simply because Ionic Compounds are POLAR molecules. There electronegativity different between the Metal and Non metal is higher than 1.7 (Extremely polar). This means putting, example NaCl (Salt), in water, will easily dissolve the NaCl into the cation and anion. Hopefully this helps.
ionic compounds are more soluble than covalent.

A hydrogen atoms binds to a carbon atom by sharing an electron pair... a covalent bond. Covalent bonds are formed by non-metals, like hydrogen and carbon; ionic bonds are formed by metals and non-metals, like NaCl.
Cl-Cl is more covalent than H-Cl

No, silicon can form only four covalent bonds.
Polar covalent. C is more electronegative than Si.
