Do radioactive isotopes have stable nuclei?Isotopes:Isotopes refer to the specific combination of protons and neutrons that can be classified in an element category. While all isotopes of an element have a numbe
However, the number of neutrons need not be the same in all the atoms of an element. Two atoms of a given element are said to be isotopes if they have different number of neutrons. The sum of number of protons and number of neutrons in an atom is known as mass number (A) of that...
The more protons and neutrons contained in an atomic nucleus, the heavier that element is. So, for example, lead has 82 protons and between 120 and 132 neutrons in its nucleus, whereas hydrogen, the lightest element, has just one proton and occasionally one or two neutrons. The number of ...
In this case, beta emission produces an atom of nitrogen 14, whose nucleus consists of 7 protons and 7 neutrons. Electrons have virtually no mass; only the mass of protons and neutrons are counted in radioactive decay 863 Words 4 Pages Decent Essays Read More Sticks George Saunders In this...

The metal tin, for example, has ten stable isotopes: atoms that have the same number of protons and electrons (50 of each) but different numbers of neutrons. Stable isotopes are ones that are happy enough to stay as they are indefinitely: they have nothing to gain by changing into a ...
The carbon-12 atom, which is still used as the standard today, contains six protons and six neutrons for an atomic mass of twelve amu. Different isotopes of the same element (same element with different amounts of neutrons) do not have the same atomic mass. Carbon-13 has an atomic mass...
The electrons though have a lower energy, and therefore are in the slow-cooling regime, while the more energetic protons are in the fast-cooling regime [31]. Radiation in the X-ray and gamma-ray bands is explained by synchrotron emission from the electrons, while the TeV emission is due ...
Physicists often state that nuclear shell structure - the way in which protons and neutrons are arranged within a nucleus - is the cornerstone of any satisfactory description of an atomic nucleus. But over the past decade it has become apparent that the ...
