- Given the following information, determine which element of the periodic table is being described as element “X.” Report your answer. Explain your reasoning by addressing each piece of evidence given. a. Element “X” is not a gas at room temperature and is best described as a metal in its only allotrope (elemental form). b. When element “X” forms a cation, its atomic radius is smaller than that of neon (Ne) however, it is notable that element “X” does not form anions as partners in ionic compounds. c. The 1st ionization energy of element “X” is greater than that of atomic aluminum (Al). d. When element “X” is degraded in the presence of hydrogen chloride (HCl), a reaction ensues leaving an amorphous colorless substance. When analyzed, this substance is found to have formed in a 1:2 mole ratio of element “X” : chlorine. Once refined, this substance is useful as a cofactor in the PCR process for DNA amplification.arrow_forwardThe majority of known noble gas compounds are those of Xenon. Why?arrow_forwardAn element "X" is an alkaline earth metal and reacts with element "Y" which is a halogen. What is the most likely formula for the iconic compound formed for the reaction of these elements?arrow_forward
