  • Chemical Periodicity

    4) Elements can be created naturally through processes such as the big bang or other methods conducted by scientists. Scientists are able to create elements by using atomic colliders and quantum calculation. One process that scientists use to create new elements is to add protons one by one into an atom. This would increase the atomic number of the element which would change the identity of the element. The addition of protons causes a repulsion between the atoms because two positive forces…
