Actinium has 36 isotopes and 7 nuclear isomers.
Actinium has 89 protons and electrons; the natural isotope 227Ac has 138 neutrons.
any nickname (and generally for the chemical elements) for actinium
Actinium is a natural chemical element, radioactive; actinium is a decay product of uranium.
Actinium, with the chemical symbol Ac, is the chemical element with the atomic number 89.
Some examples of an actininide element on the peridic table are thorium, lawrencium are actinides. To know more about actinides, follow the link below:-) Also to learn more about actinides go search it on the web google or bing!! You would find alot of information on actinides in science!!:-)
The mass number for the isotope 227Ac is 227.
Actinium is rarely used in research laboratories. Also the isotope 225Ac is used as radiations source in radiotherapy.
Actinium is a natural chemical element (the isotope 227Ac) but also can be prepared by the intermediate of nuclear reactions.
The most common isotope of actinium, Ac-227, has 89 protons and electrons and 138 neutrons.
Each isotope has a different number of neutrons; Ac-227 has 138 neutrons.Number of neutrons = Mass number of an isotope - Atomic number of the element
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 chemical symbol of actinium is Ac.The symbol of an isotope:- as superscript to the left of Ac is the atomic mass of the isotope- as subscript to the left of Ac is the atomic number 89
Actinium C was the old name of the isotope bismuth-211.
Actinium is a natural chemical element, it is not a man-made element.
Actinium has 89 protons and 138 neutrons (the natural isotope 227Ac).
Actinium has 89 protons and electrons; the natural isotope 227Ac has 138 neutrons.
Actinium is a trivalent chemical element.
