how many electrons does actinium have?
Actinium is one of the most elusive elements in the periodic table, having a number of unforeseen properties that make it an ideal candidate for scientific study. Its radioactivity and relative scarcity make it unsuited for commercial applications, but a recent discovery of the chemistry of one of its isotopes (225Ac) is opening up research into cancer therapy.
The First Ionization Energy of Actinium is 5.17 eV
An electron is the smallest of the permanent core particles in an atom. It is always provided with a negative charge (the letter e-), while the proton is given a positive charge.
Electrons are produced during the decay of other atoms, such as when a uranium atom decays into actinium. They can be added or removed from an atom to change its oxidation state.
The most common oxidation states for all elements are -4, 0 and +4, which are referred to as ionization states. Oxidation states are also sometimes referred to as the valence states because they indicate the degree of bonding between an atom and its neighboring atoms.
The atoms of actinium are characterized by a high electron affinity (kJ/mol) and a relatively low electronegativity (1.1). This means that the element is prone to recombination. These recombination events can produce toxic molecules and lead to the formation of new atoms from previously formed ones. The recombination process may also disrupt the structure of an atom.
