Thus, the two electrons in the carbon 2 p orbitals have identical n, l, and m s quantum numbers and differ in their m l quantum number (in accord with the Pauli exclusion principle). The orbitals are filled as described by Hund’s rule: the lowest-energy configuration for an atom with electrons within a set of degenerate orbitals is that having the maximum number of unpaired electrons. Primary XPS region: Co2p Overlapping regions: Co LMM, Ba3d Binding energies of common chemical states: Chemical state Binding energy Co2p 3/2 Co metal: 778. ![]() We now have a choice of filling one of the 2 p orbitals and pairing the electrons or of leaving the electrons unpaired in two different, but degenerate, p orbitals. Cobalt X-ray photoelectron spectra, cobalt electron configuration, and other elemental information. The remaining two electrons occupy the 2 p subshell. Four of them fill the 1 s and 2 s orbitals. When drawing orbital diagrams, we include empty boxes to depict any empty orbitals in the same subshell that we are filling.Ĭarbon (atomic number 6) has six electrons. There are three degenerate 2 p orbitals ( m l = −1, 0, +1) and the electron can occupy any one of these p orbitals. Because any s subshell can contain only two electrons, the fifth electron must occupy the next energy level, which will be a 2 p orbital. The n = 1 shell is filled with two electrons and three electrons will occupy the n = 2 shell. The fourth electron fills the remaining space in the 2 s orbital.Īn atom of boron (atomic number 5) contains five electrons. Thus, the electron configuration and orbital diagram of lithium are:Īn atom of the alkaline earth metal beryllium, with an atomic number of 4, contains four protons in the nucleus and four electrons surrounding the nucleus. Protons/Electrons: 27 Neutrons: 32 Shell structure: 2,8,15,2 Electron configuration: Ar3d74s2 Oxidation state: 2,3 Crystal structure: hexagonal.

The alkaline earth metal magnesium (atomic number 12), with its 12 electrons in a Ne3s 2 configuration, is analogous to its family member beryllium, He2s 2.Both atoms have a filled s subshell outside their filled inner shells. Cobalt has 27 electrons out of which 4 valence electrons are present in the 3d7 4s2 outer orbitals of atom. How many valence electrons does a Cobalt atom have?Ĭobalt has 4 valence electrons. What is the color of Cobalt?Ĭobalt is of Gray color. It is located in group 9 and period 4 in the modern periodic table. Cobalt is the 27 element on the periodic table.
