Try it on paper first. A hint, the key idea and the worked solution are here when you need them.
Give the temporary IUPAC name and symbol of the elements with , and .
Moseley found that of the X-rays of an element is a straight-line function of its atomic number : . The modern periodic law: properties are a periodic function of . Temporary IUPAC names join the roots nil, un, bi, tri, quad, pent, hex, sept, oct and enn for the digits of and add ium.
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Step 1. . un + nil + hex + ium: unnilhexium, Unh. Its permanent name is seaborgium, Sg.
Step 2. . un + nil + enn + ium: unnilennium, Une. It is now meitnerium, Mt.
Step 3. . un + bi + nil + ium: unbinilium, Ubn. No such element has been made yet.
Answer: unnilhexium (Unh), unnilennium (Une) and unbinilium (Ubn).
