Question

The ion of an element has 3 positive charge, 27 mass-number and 14 neutrons. What is the number of electrons in this ion?

Answer 1

13 will bethe number of electrons

Answer 2

Answer:

e=10

Explanation: Number of valence electrons= +3

This shows that atom had lost 3 electrons to become stable and reach the state of octet.

number of neutrons= 14

Mass number= 27

Number of electrons= 27-14

=13

so the number of electrons in the ion= 13-3

=10
