(a)
Interpretation:
The ionic compounds to be matched with its corresponding diagrams.
Concept Introduction:
In the formula of the compound, the sum of the charge of cation and anion must be equal to zero. The ration of cation and anion to be known in order to arrive the formula of a compound.
Rules for Nomenclature of ionic compounds:
- The name of the cation is followed by the name of the anion.
Covalent bonding: A covalent bond is formed by sharing of electrons (equally or partially polarized) between the two non-metals.
Octet rule: By obtaining eight electrons around the valence shell of an element, then compound satisfied the octet rule and thus, achieved the electron configuration of noble gas.
Diagrammatic representation of ionic compound used: The ions in the ionic compound are represented in spheres; where the green sphere represents the cation and the red sphere represent the anions.
(b)
Interpretation:
The ionic compounds to be matched with its corresponding diagrams.
