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.
To find the number of non-valence electrons in an atom, you first need to determine the total number of electrons in the atom by looking at its atomic number on the periodic table. Next, subtract the number of valence electrons, which are the electrons in the outermost energy level of the atom, from the total number of electrons. The remaining electrons, which are not in the outermost energy level, are the non-valence 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.
Gallium (Ga) has 3 valence electrons.
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.
There are 2 valence electrons in 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)
Two valence electrons.
