It sounds like an easy homework problem. Explain where you are stuck and perhaps I'll consider helping. Start by reading the textbook and reviewing your notes.

A metal with yellow color: Gold.
a synthetic element used in smoke detectors: Americium, i think.
and yes, alkali (or alkaline) I'm pretty sure is radioactive.
Hope I helped! :)
