What is the overall charge of 9 group with 12 protons and 1 electron? What electric charge does this group have?

To determine the overall charge of a group, you need to consider the number of protons and electrons it contains.

In this case, the group has 12 protons and 1 electron. Since protons carry a positive charge of +1, and electrons carry a negative charge of -1, we can subtract the number of electrons from the number of protons to find the overall charge.

12 protons - 1 electron = 11

Therefore, the overall charge of this group is +11. It carries a positive charge of +11.
