No, radium hydroxide is not amphoteric. An amphoteric compound is one that has characteristics of and is capable of reacting like either an acid or a base. Radium is a metal from Group 2 of the Periodic Table, and these Alkaline Earth metals form hydroxides that are definitely basic in nature. In general, amphoteric compounds will not be formed by metals at the end or through the middle of the periodic table, but will include poor metals or metalloids in their makeup. An example might be aluminum hydroxide. We see the poor metal aluminum forming Al(OH)3 molecules, which display characteristics of amphoterism. A link can be found below for more information.

Is a bicarbonate ion an amphoteric substance?
amphoteric
Why beryllium hydroxide is basic?

What happens when you mix radium with water?
A violent reaction with the formation of radium hydroxide.
What pH is radium hydroxide?
13-14
Can H2O lose a hydrogen?
Yes, H2O is amphoteric so it can lose H+ and become hydroxide. Hydroxide is represented as OH-.
Is iron III oxide soluble in sodium hydroxide?
No, it is hardly soluble in sodium hydroxide though it is amphoteric. It's better in (hydrochloric) acid.
What are the amphoteric oxides of mgo and zno?
ZnO is amphoteric- i.e. it dissolves in acids and bases. Magneisum isn't! Manganese dioxide is MnO2 disolves in potassium hydroxide. Is that what you mean?
What is the formula for radium hydroxide?
Formula: Ra(OH)2
What is the chemical formula for Radium hydroxide?
Formula: Ra(OH)2
Is Iron oxide an amphoteric oxide?
An amphoteric substance is one that can behave as a Lewis acid and a Bronsted base, iron is not amphoteric. The best examples of substances behaving as an acid and a base are found with metal hydroxides such as aluminum hydroxide and zinc hyhroxide. Only certain cations show amphoteric behavior, for example if NaOH is added in small amounts to solutions of Fe3+ and Al3+ both will initially form precipitates (rust colored iron hydroxide and white aluminum hydroxide). Because Al(OH)3 is an amphoteric hydroxide and Fe(OH)3 is not, adding more NaOH will redissolve the Al(OH)3 and leave Fe(OH)3 as an insoluble solid. Commonly encountered cations that form amphoteric hydroxides are Al3+, Cr3+, Zn2+, Pb2+, Sn4+ and Sb3+. (Source:http://employees.oneonta.edu/kotzjc/LAB/Complexation.pdf pages 28-29)

What is a substance which acts as both an acid and a base?
An example would be water which can gain a proton to form the hydroxonium ion (acting as a base) or donate a proton forming the hydroxide ion (acting as an acid). An acid is a proton donor; a base is a proton acceptor.
