- Fe³⁺, Atomic number = 26; Number of protons = 26
- Mn³⁺, Atomic number = 25; Number of protons = 25
- Co²⁺, Atomic number = 27; Number of protons = 27
- Fe²⁺, Atomic number = 26; Number of protons = 26
- Ni, Atomic number = 28; Number of protons = 28
Therefore, only Fe²⁺ has the same number of protons as Fe³⁺
