3. Which statement accurately describes the atoms of a specific element? A zinc, Zn, atom contains 30 protons inside the nucleus and 30 electrons outside the nucleus. An indium, In, atom contains 115 protons inside the nucleus and 49 neutrons outside the nucleus. A scandium, Sc, atom contains 45 electrons outside the nucleus and 21 neutrons inside the nucleus. An aluminum, Al, atom contains 27 electrons and 27 protons inside the nucleus. CLEAR ALL

plzz do all very easy , if u plan to do only 1 then skip plz do all in detail in neat and clean handwriting
