Question

the nitride ion in lithium nitride is composed of how many electrons and protons

Answer 1

The nitride ion in lithium nitride is composed of TEN (10) electrons and SEVEN (7) protons.

- The formula of Lithium Nitride is Li₃N.

- The nitride ion in this compound is N³⁻.

- The no of protons in nitride ion is 7 as a nitrogen atom contains 7 protons and there is no excess proton in nitride ion.

- The no of electrons in nitrogen atom is also seven, but nitride ion has 3 excess electrons.

- So, the total no of electrons in nitride ion = 7 + 3 = 10.

Answer 2

Answer:

7 protons + 10 electrons
