carbon has six protons and is atomic number 6. Carbon occurs naturally in three isotopes: carbon 12, which has 6 neutrons (plus 6 protons equals 12), carbon 13, which has 7 neutrons, and carbon 14, which has 8 neutrons. Every element has its own number of isotopes...
Allotropes are different forms of the same element with distinct physical or chemical properties; Isotopes are atoms of the same element with differing numbers of neutrons.
Z =atomic number = number of protons in the nucleus = number of electrons orbiting the nucleus; A = mass number = number of protons and neutrons in the most common (or most stable) nucleus. What group is CA in? calcium (Ca), chemical element, one of the alkaline-earth metals ofGroup...
Evenstarswith masses between 10 and 20 times that of the sun, reach a limit to the heavy elements they can forge (Green, Jones, 2015, pg 251), usually ending up with a core of almost pure iron. Even this heavy element isn't dense enough to prevent massive cores from further collapse...

The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that ...
