WebbAtomic Charge; If there is one electron for every one proton, the atom has no charge. For every extra electron the atom experiences a -1 charge, for every missing electron, the atom experiences a +1 charge. Therefore, an oxygen atom with 8 protons and 10 electrons would have a -2 charge.

WebbTo determine the number of neutrons in the 24Mg isotope, we subtract 12 from 24: mass number – atomic number = number of neutrons. 24 – 12 = 12. so there are 12 neutrons in this atom. All magnesium atoms have 12 protons in their nucleus. They differ only by their number of neutrons: a 24Mg atom has 12 neutrons, a 25Mg atom has 13 neutrons ... WebbWe know that the mass number (A) = number of protons + the number of neutrons, and therefore, the number of protons is equal to: p = 35 – 18 = 17, and therefore, the element is Cl The Number of Protons from Electrons For a neutral atom, the number of protons and the number of electrons are equal. This is what makes the atom charge-free.
