There are ONLY 2 valence electrons in Co, valence electrons come only from the s orbital and the p orbital, giving only 2 for Cobalt.
the outer shell of cobalt contains 9 electrons.
The neutral atom of cobalt has 27 electrons. The number can vary up or down depending on the chemistry of the sample of cobalt. A link is provided to the Wikipedia article on the element cobalt.
Take the atomic number then subtract the amount of valence electrons. Example: Number of non valence (inner) electrons in Sulfur: 16 (atomic number) - 6 (valence electrons) = 10 (valence or inner electrons)
The group number in the periodic table tells you the number of valence electrons for main group elements. The group number is the same as the number of valence electrons, except for transition metals.
3 electrons !

Two valence electrons.
the number of valence electrons is the number group on the table its on
