The formulas for the ionic compounds formed from the pair of given ions are to be written. Concept Introduction: An ionic compound is a compound that consists of ions having electrostatic interaction between them. These interactions are termed as ionic bonding. The element symbols and subscripts present in an ionic compound are represented with the help of a chemical formula. While writing the chemical formula for an ionic compound, the symbol of the metal is written first which is followed by the symbol of the non-metal. Formal charge equation can be given as: Formal charge = number of valence electrons − 1 / 2 number of shared electrons − number of unsharedelectrons or F = Z − ( 1 / 2 ) S − U where F is the formal charge, Z is the group number of the element, S equals the number of shared electrons, and U is the number of unshared electrons. The arithmetic sum of all the formal charges in a molecule or ion will equal the overall charge on the molecule or ion.

Interpretation Introduction

Interpretation:

The formulas for the ionic compounds formed from the pair of given ions are to be written.

Concept Introduction:

An ionic compound is a compound that consists of ions having electrostatic interaction between them. These interactions are termed as ionic bonding.

The element symbols and subscripts present in an ionic compound are represented with the help of a chemical formula.

While writing the chemical formula for an ionic compound, the symbol of the metal is written first which is followed by the symbol of the non-metal.

Formal charge equation can be given as:

Formal charge = number of valence electrons −1/2 number of shared electrons − number of unsharedelectrons or

F = Z − (1/2)S − U

where F is the formal charge, Z is the group number of the element, S equals the number of shared electrons, and U is the number of unshared electrons.

The arithmetic sum of all the formal charges in a molecule or ion will equal the overall charge on the molecule or ion.
