Atomic Structure

A detailed Summary of Atomic Structure


The nucleus has more than 100 protons and more than 150 neutons, the nucleus is a very small part of an atom. Both the atom and the necleus can be thought of as spheres. Then both volumes of the atom can be compared with the volume of the nucleus alone, because the volume of a sphere is proportional to the cube of its radius. The space outside the nucleus is occupied only by electrons. The observation has led to the empty space concept of matter.

Ernest Rutherford , a British physicist, performed an experiment that strongly suggested that the positive charge of an atom located in a very small nucleus. Rutherforth's experiment made use of polonium, a radioactive element that gives of positvely charged particles. These parti


Isotopes are atoms of a given element that have the same number of protons but a diferent number of neutrons.Isotopes of an element are chemically identical to each other.Theb different number of neutrons produce a different mass in each isotope. Mass is the sum of the number of protons and the number of nuetrons. Gram-atomic mass of an element is the mass of the element expressed in grams.



Some common words found in the essay are:
Ernest Ruthefold, Rutherford British, , alpha particles, mass element, nucleus atom, atomic mass unit, charge atom, metal foil, empty space, mass unit, positive charge, atomic mass,
