If cobalt atom has a charge of 3+, what will be its number of electrons? And why?​

pa help po pls

The number of electrons : 24

Further explanation  

The Atomic Number (Z) indicates the number of protons in an atom of an element. If the atom is neutral then the number of protons will be equal to the number of electrons. So the atomic number can also indicate the number of electrons.  

So atomic number = number of protons = number of electrons  

Mass Number (A) is the sum of protons and neutrons  

Mass Number (A) = Number of protons Number of Neutrons  

So that the relationship between atomic numbers and mass numbers can be formulated as follows:  

Atomic Number (Z) = Mass Number (A) - Number of Neutrons  

Cobalt has the atomic number 27

So for a neutral atom, number of electrons = number of protons = 27

Cobalt atom has a charge of 3⁺, then cobalt forms a positive ion (cation) Co³⁺ by removing 3 electrons so that the number of electrons becomes:

= 27 - 3

= 24
