A nobelium atom has 102 electrons. They are expected to be arranged in the configuration [Rn]5f 14 7s 2 (ground state term symbol 1 S 0), although experimental verification of this electron configuration had not yet been made as of 2006.

Electron atomic and molecular orbitals A Bohr diagram of lithium. In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. [1]
The f-block elements come in two series: lanthanum through ytterbium in period 6, and actinium through nobelium in period 7. All are metals. The f-orbital electrons are less active in the chemistry of the period 6 f-block elements, although they do make some contribution; [5] these are rather similar to each other. They are more active in the ...
A period 2 element is one of the chemical elements in the second row (or period) of the periodic table of the chemical elements.The periodic table is laid out in rows to illustrate recurring (periodic) trends in the chemical behavior of the elements as their atomic number increases; a new row is started when chemical behavior begins to repeat, creating columns of elements with similar properties.
It is expected that moscovium will have an inert-pair effect for both the 7s and the 7p 1/2 electrons, as the binding energy of the lone 7p 3/2 electron is noticeably lower than that of the 7p 1/2 electrons. This is predicted to cause +I to be a common oxidation state for moscovium, although it also occurs to a lesser extent for bismuth and ...
Niobium is a lustrous, grey, ductile, paramagnetic metal in group 5 of the periodic table (see table), with an electron configuration in the outermost shells atypical for group 5. Similarly atypical configurations occur in the neighborhood of ruthenium (44) and rhodium (45).
No isotopes known, Isobox does not exist: local input, per Infobox. For example: Transclusion of the isobox is suppressed (no redlink), E119: |theoretical isotopes comment=Experiments and theoretical calculations Applied: E119 and up: have no Isobox, so no isotopes lists is shown—at all. Instead, the parametertext is shown as present.
