Answer: lithium fluoride
Explanation: Lithium atom has oxidation number of +1.
Electronic configuration of lithium:
Lithium atom will loose one electron to gain noble gas configuration and form lithium cation with +1 charge.
Fluorine atom has oxidation number of -1.
Electronic configuration of fluorine:
Flourine atom will gain one electron to gain noble gas configuration and form fluoride ion with -1 charge.
In lithium fluoride the one electron from lithium metal gets transferred to fluorine atom to form .
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'.
Hence, the name of is lithium fluoride.
