Yes, it is deadly. If you managed to collect a lump of it, it is so highly radioactive that it will in a few mere seconds vaporize itself into a cloud of radioactively toxic gas at bone-evaporating temperatures.
Californium has 98 electrons and 98 protons; the number of neutrons is different for each isotope of Cf.
The Deadly Dinner Party was created in 2009.
She is dead, anyway.
There skin will kill you
Frightning, infecting, deadly
Francium was named after France, the country it was dicovered in.
Not known today but probably francium don't burn.
Francium has not applications and the oxide cannot be prepared.
Francium can form cations with the charge +1.
Francium is a metal.
Francium is a true chemical element, not an example.
We haven't sufficient francium for a measurement; also francium is autovaporized.
The chemistry of francium is not known; francium has properties similar to caesium.
Francium is very radioactive and very difficult to obtain; heating of francium due to the decay leads to instantaneous vaporization of francium.
As francium is a chemical element, it is made up of protons, neutrons and electrons.
Francium is a radioacive chemical element; francium is natural but also may be prepared in laboratory.
Francium is a solid.
