Actinium Ionization Energy
http://actinium.atomistry.com/energy.html
The Actinium Ionization Energy. Is the energy required to remove from atom one mole of electrons with subsequent production of positively charged ion of Actinium. This process can be repeated many times, but the energy cost is increased dramatically. The general equation for the Actinium is:. 499 kJ/mol = 119.38 Kcal/mol. 1170 kJ/mol = 279.90 Kcal/mol. 1900 kJ/mol = 454.55 Kcal/mol. 4700 kJ/mol = 1124.40 Kcal/mol. 6000 kJ/mol = 1435.41 Kcal/mol. 7300 kJ/mol = 1746.41 Kcal/mol.
Actinium Isotopes

There is no Actinium Stable isotopes known. There is no Actinium Natural Radioactive isotopes known. Actinium radioactive isotope number 1. Alpha; : 100.00 %;. 0022s ≈ 22.00 ms;. Actinium radioactive isotope number 2. Alpha; : 100.00 %;. 0033s ≈ 33.00 ms;. Actinium radioactive isotope number 3. Alpha; : 100.00 %;. 0011s ≈ 11.00 ms;. Actinium radioactive isotope number 4. 0027s ≈ 27.00 ms;. Actinium radioactive isotope number 5. Epsilon; : 1.00 %. 0095s ≈ 95.00 ms;. Actinium radioactive isotope number 6.
Actinium Production

Are synthesized by Radium neutron bombarding in nuclear reactors. AsAc. Compounds it is separated from Radium via extraction by thenoyltrifluoroacetone or ionites. 1 mg of actinium. May be obtained from 1 g Radium. Actinium metal. Also may be obtained via AcF. Reduction by Litium vapours. t.
Actinium Applications
http://actinium.atomistry.com/application.html
Are limited; it is mostly used as neutron source which appear by beryllium-9 alpha-particles irradiation which, in their turn, are emitted by actinium-227. However there are many reasons to consider such actinium-beryllium. Sources as not the best, not most thrifty. Research is quite important. Thus, it is the basis of Glenn T. Seaborg's theory in the chemistry of the transuranium elements, developed the actinide concept. Francium also had been discovered by observation of actinium-227.

Element Actinium, Ac, Actinide or Actinoid
Element Actinium, Ac, Actinide or Actinoid. Was discovered in 1899 in pitchblende residues by Andre-Louis Debierne, Curie's collaborator. The word actinium. After which the latter name was confirmed. Actinum. Is a member of actinide. Group of chemical elements. Isotopes with mass numbers from 221 to 230 are known. The most long-lived of them is. 218 years) which emits β-particles (98.8%) and α-particles (1.2%). Isotopes. However, comparing with other elements actinium abundance. Is extremely small, 6x10.
