QUESTION:
Problem 80P
Determine the charge of each ion.
(a) tungsten ion with 68 electrons
(b) tellurium ion with 54 electrons
(c) nitrogen ion with 10 electrons
(d) barium ion with 54 electrons
ANSWER:
Solution 80P
Step 1:
It is known that elements with more number of electrons than atomic number is a -vely charged ion and elements with less number of electrons than the atomic number is a +vely charged ion.
Hence in option
(a) tungsten ion with 68 electrons
The atomic number of tungsten is 74. In this question it has given that W atom has 69 electrons that means it loses 6 electrons and become a cation . so it is +vely charged i.e W6+
