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
Duane (given name) Duane (given name) Duane is both a given name for a male, and a family name. It seems to have a convergent etymology from several sources. The name derives from St. Dubhán, a Welsh Saint who established an abbey in Hook Head, Ireland, during the 5th century. As a surname it is O'Dubhain, or Dubhan.
