Answer:
The name of compound 'KF' is, Potassium fluoride.
The name of compound 'Mg₃N₂' is, Magnesium nitride.
Explanation:
Ionic compound : It is defined as the compound which is formed when electron gets transferred from one atom to another atom.
Ionic compound are usually formed when a metal reacts with a non-metal.
The nomenclature of ionic compounds is given by:
1. Positive ion is written first.
2. The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.
3. In case of transition metals, the oxidation state are written in roman numerals in bracket in-front of positive ions.
(a) KF
KF is an ionic compound because potassium element is a metal and fluorine element is a non-metal. The bond formed between a metal and a non-metal is always ionic in nature.
Thus, the name of compound 'KF' is, Potassium fluoride.
(b) Mg₃N₂
Mg₃N₂ is an ionic compound because magnesium element is a metal and nitrogen element is a non-metal. The bond formed between a metal and a non-metal is always ionic in nature.
Thus, the name of compound 'Mg₃N₂' is, Magnesium nitride.
