Actinium is a very reactive (but not the most) metal; the Pauling electronegativity is 1,1.
Having a Pauling electronegativity of 1,1 actinium is more reactive than other actinoids.
Actinium react with oxygen, water, hydrogen, sulfur, halogens, etc.
Actinium is a reactive metal with a Pauling electronegativity of 1,1. But the chemistry of actinium is only superficially known. Actinium easily react with oxygen, water vapors, acids. Actinium is trivalent in solutions; only in AcH2 is divalent.
Yes, but because actinium is very rare and strongly radioactive his chemistry was studied only a little.
Actinium is more dangerous than uranium.
Actinium is a radioactive metal; no taste !
fluorine is the most reactive
no actinium is not a magnet no actinium is not a magnet
The most common isotope of actinium, Ac-227, has 89 protons and 138 neutrons.
The number of neutrons is the difference between the atomic mass of an isotope and the atomic number. Actinium has a great number of isotopes, each with a different mass or number of neutrons.
The most common isotope of actinium, Ac-227, has 89 protons and electrons and 138 neutrons.
Actinium is a trivalent metal; only in the actinium hydride is divalent.
