Helium: He, 2 protons. Oxygen: O, 8 protons. Iron: Fe, 26 protons. Gold: Au, 79 protons.
The Fe(3+) cation has 26 protons, 30 neutrons (for the isotope Fe-56) and 23 electrons.
Ag+
Atomic Number: This is the number of protons an element has. Answer: 26 Atomic Mass: Ignoring electrons, which are incredibly small and don't have much of an effect on the mass... This is the number of protons plus the number of neutrons Answer: 56 (26 protons + 30 neutrons) Net Charge: Protons are positive and electrons are negative. The net charge can be found by subtracting the number of electrons from the number of protons. 0 is neutral. Answer: +3 (26 protons - 23 electrons)
This ion is yellowish brown color in water. Ion contains 26 protons.

This is the ion Fe(3+).
Fe + 3AgNO3 ==> Fe(NO3)3 plus 3Ag The oxidation number of Ag in AgNO3 (on the left side) is 1+ and in Ag (on the right side), it is zero. Thus, in this reaction, silver (Ag) has been reduced.
Use Avogadro's number. 2 mole Fe(3+) ( 6.022 X 10^23/1 mole Fe(3+) ) = 1.20 X 10^24 ions of Fe(3+)
Iron (Fe) has an oxidation number of +3 in compounds like iron(III) chloride (FeCl3).
The Fe(3+) cation has 26 protons, 30 neutrons (for the isotope Fe-56) and 23 electrons.
A. Fe^2+ ==> Fe^3+ + e- is an oxidation reactionB. Fe^3+ +e- ==> Fe^2+ is a reduction reactionC. Fe(s) ==> Fe(l) is neither an oxidation nor a reduction reaction. It is a phase change.D. Fe + 2e- ==> Fe^2+ is not a possible reaction.
Ag+
I am understanding you to mean an iron-57 ion with a charge of 3+.The atomic number of Fe is 26, which means that all Fe atoms or ions have 26 protons in their nuclei.In a neutral Fe atom, the number of electrons would be the same as the number of protons, which is 26. The charge on the Fe ion is 3+, which means the Fe atom has given up 3 electrons. So the number of electrons in an Fe3+ ion is 26-3, which is 23.The mass number of iron-57 = 57. The mass number is the sum of protons and neutrons in the atomic nuclei of iron-57 atoms. We know the number of protons is 26. The number of neutrons = mass number - the number of protons, which is 57-26 = 31 neutrons.To summarize:The number of protons in all Fe atoms is 26.The number of electrons in an any Fe3+ ion is 23.The number of neutrons in an iron-57 atom is 31.
Fe 2+ is Ferrous Fe 3+ is Ferric
