(Given : number of protons of Magnesium = 12 , Phosphorous = 15 ) . In fact, it was this tendency to burn at extremely high temperatures (reaching over 5000 degrees Fahrenheit) that led to magnesium’s use in the firebombing of Europe during World War II. ... 1. Discoverer: Marinsky, Jacob A. and Coryell, Charles D. and Glendenin, Lawerence. For most of the 16 lightest elements (up to oxygen) the number of neutrons is equal to the number of protons. Alpha decay is used as a safe power source for radioisotope generators used in artificial heart pacemakers and space probes. An element's atomic number is just the number of protons in an atom of that element. The atomic number (Z) of magnesium atom = 12 For neutral atom, Number of protons (p) = Number of electrons (e) = atomic number (Z) i.e Number of protons in the nucleus of Magnesium atom = 12 Now, for M g + 2 number of electrons = 12 -2 = 10 and the number of protons remains the same i.e 12 Thus, the correct answer is 10, 12 The Periodic Table by Energy Levels.
