The Fe(3+) cation has 26 protons, 30 neutrons (for the isotope Fe-56) and 23 electrons.
The answer is 3. Fe -> Fe3+ + 3e
26. Iron(II) has the same number of protons as iron, iron(II) , 26. In iron(III) there are only 23 electrons hence the iron atom is charged, Fe3+
When iron loses three electrons it becomes ferric (Fe3+) ion
b. Fe3 plus ions
Fe3- represents an ion of iron with a 3- charge. The symbol "Fe" refers to the element iron, and the superscript "-3" indicates that the ion carries a negative charge of 3. The 3- charge means that the ion has gained three electrons to achieve a stable configuration.
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.
The answer is 3. Fe -> Fe3+ + 3e
5 unpaired electrons There are 5 unpaired electrons in the Fe3+ ion. The reason for this is that Iron has the electron configuration Ar3d5.
The charge of the ion is 2+.This would be represented as Fe2+.
It varies. The number of electrons in an ion is equal to the number of protons minus the charge. Iron has 26 protons and will commonly form two ions: Fe2+ and Fe3+. So the number of electrons in these ions is 24 and 23 respectively.
26. Iron(II) has the same number of protons as iron, iron(II) , 26. In iron(III) there are only 23 electrons hence the iron atom is charged, Fe3+
it should lose 3 electrons
Iron (Fe), 26 electrons in neutral atom, 23 in Fe3+. Rust, Fe203 has Fe3+ ions.
Hg will have 80 electrons.
Yes. The charge of a cation tells how many more protons than electrons it has. For example Fe3+ has three more protons than electrons. However these protons were not gained, since an element always has the same number of protons no matter what its charge is. So in order for an element to have more protons than electrons it has to lose the electrons.
Iron will form a cation. Depending on how many electrons it lose, it could be Fe2+ or Fe3+. There is more than one transition state.
When iron loses three electrons it becomes ferric (Fe3+) ion
