59, atoms have an equal number of protons and electrons, keeps the charge neutral
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.
Cobalt (Co) has the atomic number 27; therefore, all neutral isotopes of cobalt have each 27 electrons. Stable cobalt exists only as Co-59 (with 32 neutrons); however, at least 28 radioisotopes of cobalt have been identified, ranging from Co-47 (with 20 neutrons) to Co-75 (with 48 neutrons).
the outer shell of cobalt contains 9 electrons.
Cobalt is a metal element. There are 27 electrons in a single atom.
Cobalt is a non metal element. There are 27 electrons in a single atom.
Every cobalt atom has 27 electrons regardless its isotope.
There are 2 valence electrons in cobalt.
