Answer:
1.This is because an atom of an element is electrically neutral , thus the atomic no. of an element ( No. of protons ) should be equal to the no. of electrons present inside an atom. But here, it is said that the Atomic no ( or no. of protons) = 12 and no. of electrons is 13.
2.Number of protons = number of electrons = atomic number Number of neutrons = mass number – atomic number Remember that Protons are Positive, and Neutrons are Neutral.
