The formulas for the ionic compounds formed between the pair of given elements are to be written. Concept Introduction: An ionic compound consists of ions that have electrostatic interaction between them which is termed as ionic bonding. The element symbols and subscripts in an ionic compound are represented by 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 unshared electrons 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.

Concept Introduction:
An ionic compound consists of ions that have electrostatic interaction between them which is termed as ionic bonding.
The element symbols and subscripts in an ionic compound are represented by 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 unshared electrons 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.
Write the formulas for the following ionic compounds: (a) sodium oxide, (b) iron sulfide (containing the Fe2+ ion), (c) cobalt sulfate (containing the Co3+ and SO4 2− ions), (d) barium fluoride.
Write the formulas for the following ionic compounds: (a) copper bromide (containing the Cu+ ion), (b) manganese oxide (containing the Mn3+ ion), (c) mercury iodide (containing the Hg2 2+ ion), (d) magnesium phosphate (containing the PO4 3− ion).
7. Isotopes. (a) Argon has three naturally occurring isotopes, 36Ar, 38Ar, and 40Ar. What is the
mass number of each? How many protons, neutrons, and electrons are present in each?
(b) Gallium has two naturally occurring isotopes, 6°Ga (isotopic mass = 68.9256 amu, abundance
60.11%) and 71Ga (isotopic mass = 70.9247 amu, abundance = 39.89%). Calculate the atomic mas
of gallium.a
%3D
(c) Chlorine has two naturally occurring isotopes, 35CI (isotopic mass = 34.9689 amu) and 3"Cl
(isotopic mass = 36.9659 amu). If chlorine has an atomic mass of 35.4527 amu, what is the percent
abundance of each isotope?
