Carbon has an atomic number of six, and two stable isotopes with mass numbers of twelve and thirteen, respectively. Its average atomic mass is 12.11. Scientists determine the atomic mass by calculating the mean of the mass numbers for its naturally-occurring isotopes. Indeed, the alarming fact is that recent presidential administrations have faced an increasing number of mass shootings: eight under Clinton, eight under Bush, and 24 under Obama (see chart below).

Characteristics of mass number. The mass number is written as a superscript on the left side of the symbol of the element. The mass number for all the elements is always a whole number. It cannot be a fraction. Though, He-4 has a mass number 4 and atomic number 2. The atomic number is 12, so it must have 12 neutrons. 24 = atomic mass( number of protons and neutrons) 24: 54.938: Manganese: Mn: 25: 55.845: Iron: Fe: 26: 58.6934: Nickel: Ni: 28: 58.9332: Cobalt: Co: 27: 63.546: Copper: Cu: 29: 65.39: Zinc: Zn: 30: 69.723: Gallium: Ga: 31: 72.64: Germanium: Ge: 32: 74.9216: Arsenic: As: 33: 78.96: Selenium: Se: 34: 79.904: Bromine: Br: 35: 83.8: Krypton: Kr: 36: 85.4678: Rubidium: Rb: 37: 87.62: Strontium: Sr: 38: 88.9059: Yttrium: Y: 39: 91.224: Zirconium: Zr: 40: 92.9064: Niobium: Nb: 41: 95.94: Molybdenum: Mo: 42: 98: Technetium: Tc: 43: 101.07 Mass number: Protons: Neutrons: Magnesium: 24: 12: 12: Potassium: 39: 19: 20: Carbon: 12: 6: 6 The mass number (symbol A, from the German word Atomgewicht [atomic weight]), also called atomic mass number or nucleon number, is the total number of protons and neutrons (together known as nucleons) in an atomic nucleus.

Mass Number: The number of neutrons does not affect the mass number of an atom. Isotopes. Atomic Number: Isotopes have the same atomic number. The mass number (A), also called atomic mass number or nucleon number, is the total number of protons and neutrons (together known as nucleons) in an atomic nucleus. The mass number is different for each different isotope of a chemical element.
