Step 1
First, we need to recall the charge of a chlorine atom and the charge of an electron. A chlorine atom has a charge of + 1 in the elementary charge scale, which means it has 17 protons and 17 electrons when neutral. An electron has a charge of - 1 in the elementary charge scale.
Step 2
Now, when a chlorine atom gains one electron, it becomes a chlorine ion with a charge of - 1 (since it now has 18 electrons).
Final Answer
The charge of a chlorine ion that has gained 1 electron is - 1.
