Radium-226 is a common isotope on earth but has a half-life of about 1600 years. why is there any radium at all?

. This is because it keeps getting halved, and something that keep getting cut in half will never reach zero.

What French scientist discovering radium?
Marie Sklodowska-Curie and Pierre Curie
What is the symbol for an atom of radium with 88 protons and 140 neutrons?
First of all there is NO reason for the plural form of this question, because every element has only ONE unique atomic number with ONE unique symbol. In this case 86RaRadium is a radioactive chemical element which has thesymbol Ra andatomic number 88 (group II, period 7 in the PS).Its appearance is almost pure white, but it readily oxidizes on exposure to air, turning black. Radium is an alkaline earth metal (like Ca and Ba).Ra is found in trace amounts in uranium ores. It is extremely radioactive. Its most stable isotope, 226Ra, has a half-life of 1602 years and decays into radon (86Rn) gas.
Who is famous for discoveries in radioactivity?
marie curie
What woman won the nobel prize for science in 1903 for discovering radioactivity?
Marie Curie (although she did not 'discover radioactivity'; that was Becquerel)
How was radioactivity discovered?
Radioactivity was discovered on March 1, 1896, by a French physicist named Henri Becquerel, this discovery is now known as one of the most famous accidental discoveries in the history of physics. Becquerel was then awarded half of the noble prize for physics in 1903, the other half being given to Pierre and Marie Curie for their study of the Becquerel radiation.
