Problem: Write the symbol for each of the following ions: (a) the ion with a 3+ charge, 28 electrons, and a mass number of 71

FREE Expert Solution

Let's start with the charge. We have a +3 charge for this ion, which means it needs 3 more electrons in order to be neutral.

Knowing this we can add 3 electrons to the given number of electrons of the ion to know what is the number of electrons for the neutral form.
