You can't have a neutral atom with a charge of +2. The symbol Ba²⁺ represents a barium ion, which has lost two electrons.

Here's why:

* Neutral Barium (Ba): A neutral barium atom has 56 electrons (the same number as protons, which defines its atomic number).

* Barium Ion (Ba²⁺): To become a +2 ion, barium loses two electrons. This means a Ba²⁺ ion has 54 electrons.
