Question

why do we have to consider the covalency number and the oxidation number of the atom in the construction of the ionic bond?​

Answer 1

We must consider the Covalency number and the oxidation number of atoms in the formation of ionic bond states:

• The state of oxidation, or the number of oxidation, is the limited charge of an atom if all its bonds in different atoms were fully iron.
• Covalency is the number of covalent bonds an atom can make with other atoms.
• Covalency is, therefore, determined by the number of electrons present in the outer orbital atom of the atom.
• Covalency is the number one covalent bond an atom can make. Therefore, covalency depends on the number of electrons in the atom that can share with other atoms.
• The oxidation state of an atom is the number of electrons found or discarded by a particular atom when forming a chemical bond.
• Covalency is the number of electrons given to an atom and other atoms to form bond bonds, e.g., Carbon can share 4 electrons, so it has 4 Covalency.
• Oxidation status The number of electrons losing an atom, eg, Na +, Na loses one electron so get a charge +, the oxidation state is + 1.
