In the Ground-State Electron Configuration of Fe3+ How Many Unpaired Electrons are Present

Atomic number of Fe is 26. Electron configuration of Fe is 1s2 2s2 2p6 3s2 3p6 4s2 3d6. Fe3+ ion has 26-3=23 electrons. Which means that, Fe3+ has an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s0 3d5. In the ground-state electron configuration of Fe3+, 5 unpaired electrons are present.

Let’s start with iron metal. The symbol for the element iron is “Fe”. The 4th period is a transition element belonging to the 8B group. It has an atomic number of 26 and an atomic weight of 55,845. It is in the solid phase at room temperature. Its density is 7.874 grams/cm3. Its melting point is measured at 1811K (1538°C or 2800°F). Its boiling point is known as 3134K (2861°C or 5182°F).[1]

Iron is the most used and least expensive metal. It is a shiny, ductile, malleable and silver-gray metal. It is known to exist in four different crystal forms. It rusts in moist air, not in dry air. It is easily soluble in dilute acids. Iron is a chemically active metal and forms two major series of chemical compounds; divalent iron (II) or ferrous compounds and trivalent iron (III) or ferric compounds.

In this article we will try to find an ” In the Ground-State Electron Configuration of Fe3+, How Many Unpaired Electrons are Present? “.

Fe3+ unpaired electrons

Fe3+ unpaired electrons are 5 in total. Because Fe3+ gave 3 electrons away to become an ion. Fe atom has 26 electrons in total and when it gives 3 electrons away, electron number decreases to 23. Fe3+ has 23 electrons and to find out unpaired electrons we need to check the electron configuration for Fe3+. The last shell of Fe3+ is 3d5. Which means that Fe3+ ion has 5 unpaired electrons.

Ground-state electron configuration of Fe3+

Ground-state electron configuration of Fe3+ is 1s2 2s2 2p6 3s2 3p6 4s0 3d5. Because the electron configuration of Fe is 1s2 2s2 2p6 3s2 3p6 4s2 3d6. When Fe loses 1 electron, the electron configuration becomes : 1s2 2s2 2p6 3s2 3p6 4s1 3d6. Why did Fe lose an electron from 4s shell? Because 4s has lower energy than 3d shell. Fe ion wants to get rid of 4s first to reach to a higher energy level. That’s why Fe loses its electron from 4s shell.

When Fe loses 2 electrons, the electron configuration becomes : 1s2 2s2 2p6 3s2 3p6 4s0 3d6. And finally, when Fe loses 3 electrons, the electron configuration becomes 1s2 2s2 2p6 3s2 3p6 4s0 3d5. It’s the ground-state electron configuration of Fe3+ ion.

What is the electron configuration for the fe3+ ion?

Electron configuration for the Fe3+ ion is 1s2 2s2 2p6 3s2 3p6 4s0 3d5.

What is the ground-state electron configuration of Fe3+?

Fe ion, Fe3+ wants to get to a higher energy level by giving its electrons. +3 means that Fe gave 3 electrons away. Fe can give electrons from 4s shell first. So if we want to find the ground-state electron configuration of Fe3+, we need to give electrons from 4s shell first. The ground state electron configuration of Fe3+ is 1s2 2s2 2p6 3s2 3p6 4s0 3d5.

How many unpaired electrons are present in the ground-state of Fe3+ Fe 26

5 unpaired electrons are present in the ground-state of Fe3+ Fe 26. Because ground-state of Fe3+ has 23 electrons and when we write down the electron configuration of Fe3+, we can see that the last shell is 3d5. It means that there are 5 unpaired electrons in the ground-state of Fe3+.

Fe3+ electron configuration

Fe3+ electron configuration is 1s2 2s2 2p6 3s2 3p6 4s0 3d5. Because Fe atom has 26 electrons and when it becomes Fe3+ ion, it gives 3 electrons away. Because electrons are negatively charged and when an atom gives an electron, it becomes positive. Fe3+ has 23 electrons which makes the electron configuration of Fe3+ is 1s2 2s2 2p6 3s2 3p6 4s0 3d5.

Fe3+ lewis acid or base

A Lewis Acid accepts electron pair while a Lewis Base donates electron pair. It means that Fe3+ is a Lewis Acid because it has empty orbital that can accept electron pairs. To understand it better, we need to write down the electron configuration for Fe3+. Electron configuration for Fe3+ is 1s2 2s2 2p6 3s2 3p6 4s0 3d5. It’s now easier to see that Fe3+ can accept electrons to its 4s orbital because it’s empy. It makes Fe3+ a Lewis Acid.

Identify the lewis acid in the following reaction: fe3+(aq)+6h2o(aq)⇌fe(h2o)63+(aq)

Fe3+ is the lewis acid in the following reaction : fe3+(aq)+6h2o(aq)⇌fe(h2o)63+(aq). Because Fe3+ accepts electron pairs. A Lewis acid is the one which accepts electron pairs.
