The number of protons in an element is the atomic number of the element, and it is not affected by the charge on the element. Hence, the species which has similar Number of proton is Fe²⁺
To know the species which the same number of protons as Fe³⁺, we need to obtain the <em>atomic number of the elements on the periodic table</em> :
- 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⁺

The element that would melt at a higher temperature than the standard temperature is iron (Fe).
<h3>Melting point</h3>
The term melting point refers to the point where a solid is converted to a liquid. A pure substance has a sharp melting point while an impure substance melts over a temperature range.
Metals have a very high melting point hence the element that would melt at a higher temperature than the standard temperature is iron (Fe).
Missing parts:
At standard pressure, which element has a melting point higher than standard temperature?
(1) F2 (3) Fe
(2) Br2 (4) Hg
