All the elements has an atomic weight; sometimes for the unstable radioactive elements is indicated only the value of the Atomic Mass of the most stable isotope.
The term atomic weight is used for elements and the term atomic mass for isotopes (after the rules and the tradition of IUPAC).
See the link below for the masses of all radium isotopes.
Barium (Ba), Radium (Ra) have atomic masses greater than strontium.
The relative atomic mass of radonis indeterminiate because this element is relatively short lived and exists only as a transient decay product.
No. In fact radium is at the bottom of the periodic table where the heaviest elements are. Its atomic number is 88 (compare with carbon, the standard element; atomic number 6)
Polonium is a rare radioactive element with symbol Po and atomic number 84. It was discovered by Marie Curie and her husband Pierre Curie in 1898. Radium is another radioactive element with symbol Ra and atomic number 88. It is also discovered by Marie Curie, and both polonium and radium are highly toxic and carcinogenic.

Radium. Elements with an atomic number greater than 83 are always radioactive.
Radium is a non metal element. Atomic number of it is 88.
Radium typically has 138 neutrons. This is derived by subtracting the atomic number (88) from the atomic mass (226) of radium.
The atomic mass of radium is approximately 226 atomic mass units.
The atomic number of radium is 88.
