what is the electron arrangement and electron configuration of Fe3+?
it loses 3 electrons so is it vanadium....
please explain.. by the way is this a transition metal? if so are there any rules?......
i don't understand!!!
Yes, Fe is a 3d transition metal.
Fe has an electron configuration of
1s2 2s2 2p6 3s2 3p6 3d6 4s2.
Fe loses the two 4s electrons to become Fe^2+.
Fe loses the two 4s and one of the 3d electrons to become Fe^3+.
No it doesn't become vanadium. The "element" is determined by the number of protons and Fe did not lose any protons in becoming either Fe^2+ or Fe^3+. Fe became either a 2+ ion or a 3+ ion by losing electrons, not protons. Loss or gain of electrons makes elements into ions; you must make nuclear changes to change the element. I assume you are thinking that if Fe loses 3e that makes it have 23 electrons which is, of course, the same number of electrons in a NEUTRAL vanadium ATOM. But the number of electrons simply determines the charge on the atom/ion; not the number of protons in the nucleus.
The electron arrangement and electron configuration of Fe3+ can be determined by considering its atomic number and the fact that it has lost three electrons.
Iron (Fe) has an atomic number of 26, meaning that it has 26 electrons in its neutral state. When Fe loses three electrons to become Fe3+, the number of electrons decreases to 23.
To determine the electron configuration of Fe3+, we can start by understanding the general electron configuration pattern. The electron configuration of an element can be written using the Aufbau principle and the periodic table.
First, let's write the electron configuration of neutral Fe:
1s2 2s2 2p6 3s2 3p6 4s2 3d6.
Now, since Fe3+ lost three electrons, we remove them from the outermost energy level, which is the 4s2. Therefore, the electron configuration of Fe3+ becomes:
1s2 2s2 2p6 3s2 3p6 3d6.
Note that Fe3+ is indeed a transition metal. Transition metals are elements located in the d-block of the periodic table, and they have partially filled d orbitals in their electron configuration. Iron (Fe) is the 26th element on the periodic table and is considered a transition metal.
To determine if an element is a transition metal, you can refer to its position in the periodic table. Elements located in the d-block (groups 3-12) are generally considered transition metals.
In summary, the electron arrangement or electron configuration of Fe3+ is 1s2 2s2 2p6 3s2 3p6 3d6.
