The atomic age was born there is no deny that seems moment the shadow of the atom bomb has been across all alive a many good hope that a realistic control atomic weapons can and will be achteved meanwhile good sense required that all of us repared for any eventrality but wisdom demand to that we take time to understand this force ,because here impact the answer adream as old as man him self . A giant of limit less power at mans command and where was it science found the giant. In the atom a particel show infinite small takes on one hundred billion atom to make a head of a pin. Just the order million in the part billion of atom of tiny building blocks which make up everything in the world shape and shoes and sealing weak and cabbages and tiny although know when has even seen the atom. Saintis declared on the great deal about how it be have and there a widely accepted as the what they like, lets start by hiding a leading thought they as subject doc atom now observing professor him self we can see that his structure as sample in many ways something almost this those the atom is small. The solar system and there are certain similarity his in the center with the electron in sorounding orbit but where as the planets movement trans is slighthy differeat there are other differences two. Hey i hold it. Thx u. Now the solar system eather is electrical the electron with charge negative are attracted by the proton with change positive. Heres the nucleus are other particles with no electrical charges called neutron. Very important caracters too as we as see, and equaly important. When it comes to atomic energy is what scientis call the atom binding force. Its a kind of cosmc glue holding the nucleus together. This then is single atom but certainly not all atom are a like. There are in nature more than ninety basic elemens which the science term for familys of atom. The scientis the atoms of individual atom familys or elemens are identified by number that is the number of proton or positive charge in the nucleus and they very all the wins from a hidrogen which has just one proton to oxygen with 8 protons gold his reach was 79 . finally on the heaviest of all natural elemens uranium 92 proton now within each elemen are family of atoms they can be different members each one having the same number of protons but different in the number of neutron . the total of an atom proton and neutron. Is atomic weight these in natural Uranium have U-234, U-235, U-238 this different member of the same element or atom funny science called isotop. Some element in for intances hve grade many of isotop. Others like almunium are aone with just one no most ato of most elements ar contain with there living life. We speak of them as being stable but other a busy day and night beinng what science called radioactive like radium throwing of powerful raise along with some love it neutrons and protons unil atually alters itss own nuuclear struct. And changes to another family the end then to another until it does became stable at last. This spontaneous changing up element is called natural transmutation. Its discovery gave mean of science and idea. If an atom could change in atom using is built very particle which radium through of noted british scientist bombarded nitrogen. An inverted to oxygen in terms of individual atoms. This is what happened the radium nucleus. Turning it to oxygen. This was artificial transmutation mean changing the element. From the first experiment others by the thousand followed as scientist devised ever more powerfull particle accelerators commonly called atom smashers to transmute more and more kinds a bad image. All scientfically important but hardly world shating then in 1939 some scientist were experimentig with transmutation up uranium but would happen they wondered if they fired a neutron, at a uranium nucleus already the heaviest in nature why not try so they dry on and the result nuclear fission instead of a mnor change the atom split into truly a discovery to change the world. For what had happened when the uranium atom spilt was aa kind a double miracle of science have america concern that binding force. We spoke up before that kind a cosmc louis which holds the atoms nucleus together. We still dont know all abut that binding force, but we do know it is equivalent to most. Therefor we mean is speak up it is having a kind of weight have ts own now the two atoms into which uranium atom spilts also have binddig force. Just for some reason it takes less so that glue to hold them together, and in the process of fission a tiny fraction is left over what happens to it being it explodes as energy roving einstein eexperience the mass and energy are really the same but we spoke about double miracle.
