Question

When a lithium ion and nitrate ion combine, the result is:

LiNO3

Li2NO3

LiNO2

Li2NO2

Answer 1

LiNO3; nitrate has a charge of -1, and lithium has a charge of +1

Answer 2

Answer: Option (a) is the correct answer.

Explanation:

A lithium atom has atomic number 3 and its electronic distribution is 2, 1. Therefore, it easily loses one electron and results in the formation of $Li^{+}$ which is known as lithium ion.

Whereas a nitrate ion has a chemical formula as $NO^{-}_{3}$.

Since, charge on both lithium and nitrate ion is same in number. Therefore, when both these ions combine together then it results in the formation of $LiNO_{3}$ compound.

Name of this compound is lithium nitrate.

Thus, we can conclude that when a lithium ion and nitrate ion combine, the result is $LiNO_{3}$.
