The Atomic Age

It was held six days after bomb material became available. After the experiment and careful planning, the Hiroshima bomb is ready to explode. Hiroshima and Nagasaki were peaceful cities before the explosion, but they were chosen because of their high military value. Hiroshima City is on the flat land of the Ota River Delta, and the city area is over 26 square miles. There is no separation of commercial, industrial and residential areas. 75% of the population is located in the center of the city.

The atomic era of the atomic era, which consists of complicated and controversial issues, has greatly changed our way of life and our way of living. * What is the cause of atomic bombing? The answer to this question thinks of events that deal with controversial issues about nuclear power, the Manhattan plan, and when, where, how, how and how to use bombs. - atoms At minimum to maximum, each atom (excluding noble gas) has the same desire: to have a complete octet, meaning that the eight electrons meet the valence shell. why? As you are unstable when something is missing in life, atoms are unstable because they lack the necessary 8 electrons. But these atoms are smart and find ways to get what you want. What they are doing is the chemical bond we are talking about today.

Under normal circumstances, atoms usually do not change. If you have a type of atom, it is possible to hold this type of atom. If the elements have unstable nuclei, they can be changed by the main nuclear process. Electrons are the most easily modified elementary particles. What does these changes mean? Changes in neutrons change the atomic weight of the element, but its identity does not change. Isotopes (same protons, different neutrons) all have the same type of atomic nature and behavior except for one atomic weight. Isotopes of some elements have special properties that are useful in magnetic resonance imaging. Heavy isotope reaction is slightly slow
