Web30 de ago. de 2024 · By far the largest atom illustrated in these color plates is Li. Because Li has an electron in the n = 2 shell, it is larger than H or He whose 1 s electron clouds are much closer to the nucleus. Li is also larger than Be, B, or C. The way the atomic radius varies with increasing atomic number can be explained by the arrangement of electrons in shells of fixed capacity. The shells are generally filled in order of increasing radius, since the negatively charged electrons are attracted by the positively charged protons in the nucleus. As the atomic number increases along each row of the periodic table, the additional electrons go into the same outermost shell; whose radius gradually contracts, due to t… WebYes, uranium-238 (Z=92) is the heaviest naturally-occurring element on Earth.
