To discover the elements, researchers at the three labs slammed lighter nuclei into one another and looked for radioactive decays that should come from the new elements. Ununtrium and ununpentium are thought to be metals. Ununseptium could be a metalloid. The fourth element, ununoctium, may be a gas, like other elements, helium, neon and argon. It is hard to know for sure because so few atoms of each element have ever been made. Paul Karol, chair of the IUPAC panel that verified the elements, said: “It will be a long time before we can find practical uses for the new elements.”
What does Paul Karol say about the new elements?
They will not be utilized for a while They will be used in practice before too long They do not have radioactive decays They reflect huge progress in the chemistry fiel
