Fe Full Form

What is the full form of Fe?

This abbreviation is a representation of Ferrum, which is the Latin word for Iron. ‘Fe’ is the symbol for the 26th element in the periodic table. Usually, in the periodic table, the chemical elements are represented using their Latin words. Iron is considered one of the most common elements present on earth. It is the fourth most abundant element in the Earth’s crust. The presence of this metal in the outer and inner core of the planet makes Iron an essential element. It also has a significant biological function. Fe constitutes a part of the oxygen carriers such as haemoglobin and myoglobin inside our blood. Therefore it plays a crucial part during oxygen transportation.

Electronic Configuration

The number of electrons in Fe is 26. These will arrange themselves in orbits around the nucleus of the Fe atom. There are four subshells: s, p, d, and f. The s subshell can hold only 2 electrons. Thus, the first 2 electrons will go to 1s (first orbital of the s subshell). The following 2 electrons will move to the 2s (second orbital of the s subshell). The p subshell can hold a maximum of 6 electrons. Thus 6 electrons move to the 2p subshell. Then 2 electrons will move to 3s orbital. The following six will move to 3p orbitals. The following shifts to 4s orbital, and the rest moves to 3d orbitals. The subshells sometimes need to be disordered, and this is to conserve energy. The subshells with lower energy are usually completed first, and then they will move to higher energy levels.

The electronics configuration of Fe can be written as:

1s^22s^22p^63s^23p^63d^64s^2 Or, [\mathrm{Ar}] 3 \mathrm{~d}^6 4 \mathrm{~s}^2

Features:

Appearance

Iron has a smooth surface resembling a silver-grey polished mirror. It readily reacts with water and oxygen to produce iron oxides which are usually observed as rust. During rust formation, this metal flakes off and exposes the new surface to water and oxygen, and that is how metal items get destroyed by corrosion.

Uses

Iron can be mixed with other elements to form alloys. These alloys help to elevate the features, particularly the strength of the metal. They can then be used in building bridges and bicycle chains.
