26
The element with the proton number of 26 is Fe, which is Iron
The element with 26 protons is iron (Fe).
The proton number for an isotope of iron with 59 mass number would be 26, as iron has 26 protons in its nucleus. Since the mass number is 59 and the proton number is 26, the number of neutrons would be 33 (59 - 26).
In Fe^1-, the 1- charge indicates that the iron atom has gained one extra electron. Therefore, the number of protons remains the same at 26, while the number of electrons increases by one to 27.
It doesn't matter if it's 56Fe or 49Fe; the number of protons in an atom of iron will remain constant. Why? Because if there was one more electron, it wouldn't be Fe anymore: it'd be cobalt (Co). The number of protons determines the element, the only thing that can change regarding the nuclear makeup of an atom without changing the element is the number of electrons. The 56 stands for the atomic weight of that particular isotope of iron. If each neutron and each proton weigh 1 amu each, then the atomic weight minus the number of protons will give you the number of neutrons.
The number of protons in Iron is 26
There are similar number of protons in the ion and the atom. Fe+3 ion contains 26 protons.
The element with the proton number of 26 is Fe, which is Iron
The symbol for iron is Fe from the Latin word ferrum meaning iron. there are 26 protons in iron.
Iron (Fe): atomic number 26 and of course has 26 protons.
In a neutral iron (Fe) atom, the number of protons is 26, which is the atomic number of iron. The number of neutrons can vary, but the most common isotope of iron, Fe-56, has 30 neutrons. Since the atom is neutral, it will have an equal number of electrons as the number of protons, so it also has 26 electrons.
This ion is yellowish brown color in water. Ion contains 26 protons.
The element with 26 protons is iron (Fe).
Iron (Fe) has 26 protons.
Helium: He, 2 protons. Oxygen: O, 8 protons. Iron: Fe, 26 protons. Gold: Au, 79 protons.
The number of Neutrons and Protons in the nucleus.So it would be 26 Protons and 30 Neutrons so...26+30=56<so that is the mass number.
We can answer this, and the same for any element, by looking at a Periodic Table. Let's start simple and look at Carbon. It's element number 6 in the periodic table. This means it has 6 protons. It's that simple. So, Fe? Fe is number 26. It has 26 protons. That's all. It also has 26 electrons. These questions really are as easy as they seem, so don't be put off.
