An element has 13 protons, 12 neutrons, and 13 electrons. The atomic charge will be positive because it can donate a proton. The correct option is A.
What are atomic charges?
Atomic charges are the charges that are given to the elements or ions when they donate or get an electron from another element. The charge of negative is given to the element and takes an electron from the element to complete your octave.
The positive charge is given to the ions when you donate an electron or more electrons to another element. The charge number will increase with the increases in donating or acceptance of electrons.
When an element has 13 protons, 12 neutrons, and 13 electrons. It has 13 electrons on its outer shell, which means it can donate electrons so it will get a positive charge.
Thus, the correct option is A. positive.
