Atomic radius and electrons because opposite charges attract, and more protons creates a stronger charge. The greater attraction draws the electrons closer to the protons, decreasing the size of the particle. Therefore, atomic radius decreases. Down the groups, atomic radius increases. This is because there are more energy levels and therefore a greater distance between protons and electrons. In addition, electron shielding causes attraction to decrease, so remaining electrons can go farther away from the positively charged nucleus. Therefore, size (atomic radius) increases. The following table summarizes the main phenomena that influence the atomic radius of an element: The electrons in the
How to Photograph an Atomic Bomb A traveling exhibit based on the book was purchased by the Atomic Testing Museum and put on display in 2007. In 2010, "The New York Times" featured a 23-image slideshow on its website with photos taken from the book accompanied by an audio recording of George Yoshitake, then one of the few surviving cameramen. How to Photograph an Atomic Bomb How to Photograph an Atomic Bomb is a book written by Peter Kuran and published in 2006 by VCE. It documents the stories of the men who photographed US nuclear weapons tests between 1945–1963 and the techniques they used to
