There are 25 protons in an atom of Mn-51 even if the atom has a charge of +1. The proton number also defines the atomic number of an atom.
Explanation:
The proton number of the atoms of an element never change without changing the type of atom/ element. Therefore, in other words, the atomic number (which is equivalent to proton number) remains the same across all isotopes of an element. Even when the atoms lose some electrons, the proton number remains the same.
Manganese (Mn) has atomic number 25. Meaning it has 25 protons. This proton number remains the same even if the Mn atoms are charged.
