Question.    Atomic Mass Nuclear stability is a concept that helps to identify the stability of an isotope. According to the Einstein relationship (E=mc2), this binding energy is proportional to this mass difference and it is known as the mass defect. The atomic mass is carried by the atomic nucleus, which occupies only about 10-12 of the total volume of the atom or less, but it contains all the positive charge and at least 99.95% of the total mass of the atom. As a result of this expansion, the density of most materials decreases. The chemical symbol for Yttrium is Y. Proton and electrons are charged particles, the first one is said to be positive and the latter negative. How many protons electrons and neutrons are in carbon? Neutrons are relatively stable mean life ~ 881 seconds. The classical description cannot be used to describe things on the atomic scale. The atomic radii decrease across the periodic table because as the atomic number increases, the number of protons increases across the period, but the extra electrons are only added to the same quantum shell.
