Explanation:

The nomenclature of ionic compounds is given by:

1. Positive is written first followed by the oxidation state of metal in roman numerals in square brackets.

2. The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.

The naming of covalent compound is given by:

1. The less electronegative element is written first.

2. The more electronegative element is written second. Then a suffix is added with it. The suffix added is '-ide'.

If atoms of an element is greater than 1, then prefixes are added which are 'mono' for 1 atom, 'di' for 2 atoms, 'tri' for 3 atoms and so on.

a) Barium chloride is an ionic compound and the chemical formula will be

b)  Magnesium-nitride is an ionic compound and the chemical formula will be

c) Sulfur dioxide  is a covalent compound and the chemical formula will be

d) Nitrogen trichloride is a covalent compound and the chemical formula will be

e) Dinitrogen trioxide is a covalent compound and the chemical formula will be

f)  Tin(IV) chloride is an ionic compound and the chemical formula will be

quartz

explanation:

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.
