WebNov 14, 2024 · The atomic radius is the size of the atom, typically measured by the distance from the nucleus of the atom to the electron clouds around the nucleus. As there are no physical existence of orbital in atoms, it is difficult to measure the atomic radius. Thus sometime different methods are used to measure the radius while they are bonded in a ... WebThe protons in the nucleus of an atom are positively charged, and want to draw in the electrons surrounding it. The more electrons there are (and the more shells that exist between the nucleus and valence shell), the harder it is for this goal to be accomplished. This results in some atoms having a larger atomic radius than others. the thing ii
