截至1949年年底为止,人类所知道的化学元素,共计只有九十六种,其原子序数由1(氢)至96(鉒)。今年年初,却在美国又从原子能研究中发现了两种新元素,其原子序数分别为97及98。元素97,是美国原子核化学家G.T. Seaborg, A. Ghiorso,及S.G. Thomson三个人,於1950年3月, As of the end of 1949, there were only 96 types of chemical elements known to humans, and their atomic number ranged from 1 (hydrogen) to 96 (helium). Earlier this year, two new elements were discovered in the United States from the study of atomic energy. Their atomic numbers were 97 and 98, respectively. Element 97, the three American nuclear chemists G.T. Seaborg, A. Ghiorso, and S.G. Thomson, was born in March 1950.
