Question

Which is more ionic ${\text{NaCl}}$ or ${\text{CuCl}}$

Answer 1

As we know that iIn chemistry, the periodic table plays a vital role. In the periodic table there are totally $118$ elements. In the periodic table there are totally $18$ columns and $7$ rows. The columns are called groups. Hence, $18$ groups in the periodic table. The rows are called periods. Hence, totally $7$ period in the table. Copper is one of the metallic elements in the periodic table. It is present in the first transition series. Each element in the periodic table has a certain group and period. In that case copper is one of the elements in the period. The atomic number of copper is $29$ and the symbol of copper is ${\text{Cu}}$. The mass number of copper is$63.5$. The general electronic configuration of copper in ground state is ${\text{1}}{{\text{s}}^{\text{2}}}{\text{,2}}{{\text{s}}^{\text{2}}}{\text{2}}{{\text{p}}^{\text{6}}}{\text{3}}{{\text{s}}^{\text{2}}}{\text{3}}{{\text{p}}^{\text{6}}}{\text{3}}{{\text{d}}^{\text{9}}}{\text{4}}{{\text{s}}^{\text{2}}}$. Because of stability we can change the electronic configuration of copper is ${\text{1}}{{\text{s}}^{\text{2}}}{\text{,2}}{{\text{s}}^{\text{2}}}{\text{2}}{{\text{p}}^{\text{6}}}{\text{3}}{{\text{s}}^{\text{2}}}{\text{3}}{{\text{p}}^{\text{6}}}{\text{3}}{{\text{d}}^{10}}{\text{4}}{{\text{s}}^1}$.

Complete answer:
The molecular formula of sodium chloride is ${\text{NaCl}}$.
The molecular formula of copper chloride is ${\text{CuCl}}$.
The formation of sodium chloride is due to the electrostatic force of attraction between the sodium ion and chlorine ion in the sodium chloride. Hence, sodium chloride comes under the ionic bond.
The formation of copper chloride is due to the mutual sharing of electrons between the copper atom and chlorine atom in the copper chloride. Hence, copper chloride comes under the covalent bond.
According to the above discussion, we conclude sodium chloride is due to ionic bond and copper chloride is due to covalent bond.
Hence, ${\text{NaCl}}$ is more ionic than${\text{CuCl}}$.

Note:
We need to know that the atomic number of the element is nothing but the number of electrons or number of protons. The mass number of the atom is nothing but the sum of the number of protons and number of neutrons. Copper is one of the transition metals in the period. The nature of the copper is metallic solid. In the modern period, copper plays a vital role in industrial development. In our body also copper plays a vital role through haemoglobin in the blood.
