In some cases yes but alkali metals are elements that have 2 valence electrons so they are very reactive. Some examples are Calcium and Radium.
Radium is a natural chemical element, an alkali earth metal; but some isotopes of radium can be obtained artificially.
No, rubidium is not considered a transition metal. It is not located in the periodic table where the other transition metals are, which is mainly the d-block.

A metal is a base and is an alkali
metal
Yes. Radium is a highly radioactive alkali earth metal, and inhalation, injection, ingestion or body exposure to radium can cause chemical burns, radiation burns and can lead to cancer and other disorders. Radium is chemically similar to calcium, and it has the ability to replace calcuim in bones, which is extremely harmful. A link is provided to the Wikipedia article on radium.
