Chemists have determined that elements with atomic numbers greater than 92 are all radioactive. In general, their half-lives are much shorter than the age of the universe. This means that they no longer exist in nature and have all been artificially produced by scientists in nuclear reactions. Elements 93 through 105 in the periodic table have been created and named, and scientists have claimed discovery of elements 106 and 107. The transuranium elements, as they are called, become less stable as the atomic number and mass increase. For example element number 93, neptunium, has a half-life of two million years, while element number 104. kurchatovium, has a half-life of 70 seconds. The transuranium elements are the heaviest elements that exist and are readily fissionable when subjected to nuclear bombardment. Chemists studying these elements and the periodic table predict that stable elements may be found around atomic numbers 114 or 126. 36.

Question

Chemists have determined that elements with atomic numbers greater than 92 are all radioactive. In general, their half-lives are much shorter than the age of the universe. This means that they no longer exist in nature and have all been artificially produced by scientists in nuclear reactions. Elements 93 through 105 in the periodic table have been created and named, and scientists have claimed discovery of elements 106 and 107. The transuranium elements, as they are called, become less stable as the atomic number and mass increase. For example element number 93, neptunium, has a half-life of two million years, while element number 104. kurchatovium, has a half-life of 70 seconds. The transuranium elements are the heaviest elements that exist and are readily fissionable when subjected to nuclear bombardment. Chemists studying these elements and the periodic table predict that stable elements may be found around atomic numbers 114 or 126. 36. According to the passage, what can we predict about the half-life of element number 105? It is: A. measured in days or weeks B. less than 70 seconds C. incalculable (not capable of being determined) D. greater than the other transuranium elements E. greater than 2 million years 37. Based on the information in the passage, which of the following relationships appears to be true for those elements 93 through 105? A. The greater the atomic number, the higher the half-life. B. The greater the atomic number, the lower the half-life. C. The greater the radioactivity, the greater the half-life. Please help question 36 and 37
