actinium's Usage Examples:

Protactinium (formerly protoactinium) is a chemical element with the symbol Pa and atomic number 91.

Debierne found and called actinium.

In 1939, Perey discovered the element francium by purifying samples of lanthanum that contained actinium.

This compound was made by heating actinium.

While working at the Kaiser Wilhelm Institute on radioactivity, she discovered the radioactive isotope protactinium-231.

233Pa has convenient half-life and energy of γ-radiation, and thus was used in most studies of protactinium chemistry.

In particular, the lattice constants of the analogous lanthanum and actinium.

The primary decay products before 237 Np are isotopes of uranium and protactinium, and the primary products after are isotopes of plutonium.

Next, with a short half-life, 234Th nuclei emit a beta particle to become protactinium-234.

The actinoid series derives its name from the first element in the series, actinium.

Actinium(III) oxide is a chemical compound containing the rare radioactive element actinium.

in 1917/18 by Otto Hahn and Lise Meitner, and they chose the name proto-actinium, but the IUPAC finally named it "protactinium" in 1949 and confirmed Hahn.

able in 1927 to isolate protactinium oxide and was later able to produce metallic protactinium by decomposition of protactinium iodide.
