Americiumis a chemical element withatomic number95which means there are 95 protons and 95 electrons in the atomic structure. The electron configuration can be visualized as the core electrons, equivalent to thenoble gasof the preceding period, and the valence electrons (e.g. In nuclear industry cadmium is commonly used as a thermal neutron absorber due to very high neutron absorption cross-section of 113Cd. Thechemical symbolfor Fermium isFm. The electronic configuration of Rhodium is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d8 5s1. Being a typical member of the lanthanide series, europium usually assumes the oxidation state +3. It is a member of the chalcogen group on the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds. Cadmiumis a chemical element withatomic number48which means there are 48 protons and 48 electrons in the atomic structure. Francium is the second-least electronegative element, behind only caesium, and is the second rarest naturally occurring element (after astatine). Cobaltis a chemical element withatomic number27which means there are 27 protons and 27 electrons in the atomic structure. An atom of an element in a compound will have a positive oxidation state if it has had electrons removed. In heavier elements, other more complex effects can also be important, leading to some of the additional anomalies.

This is important when describing an electron configuration in terms of the orbital diagrams. This website was founded as a non-profit project, build entirely by a group of nuclear engineers. One electron must be paired with another in one of the 2p orbitals, which gives us two unpaired electrons and a 1s22s22p4 electron configuration.
