The size of atoms varies by only a facto sy*;t/kxt lb1r of thrjoor- 3gb 8:hpx8;w-h(d 3wzpoa xcu.ee or so, from largest to smallest, yet the number of electrons varies - 88ob.cd o-ppahgx wh3x :(jwuor3z;from one to over 100. Explain.
参考答案:
As the number of electrons goes up, so does the number of protons in the nucleus, which increases the attraction of the electrons to the center of the atom. Even though the outer electrons are partially screened by the inner electrons, they are all pulled closer to the very positive nuclei of the large Z atoms when compared to the low Z atoms. This keeps the atom from expanding in a “linear” fashion as larger numbers of electrons are added to the large Z atoms.
