Simple ions include Na +, Ca 2+, and Cl –. Polyatomic ions include (NH 4) +, (CO 3) 2-, and OH –. Unlike protons and neutrons, electrons can be easily removed and added to an atom. Ions are formed as a result of this addition or removal of electrons from the atom.

For the Fe3+ ion we remove a total of three electrons (two from the 4s2 and one form the 3d6) leaving us with 1s 2 2s 2 2p 6 3s 2 3p 6 3d 5 1s2 2s2 2p6 3s2 3p6 3d5. The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom.

The most common iron-containing ore is haematite, but iron is found widely distributed in other minerals such as magnetite and taconite. Commercially, iron is produced in a blast furnace by heating haematite or magnetite with coke (carbon) and limestone (calcium carbonate).

Iron has the electron configuration [Ar]4s23d6. To form the 2 ion the iron atom loses the 4s2 electrons. When forming the 3 ion the iron atom loses the 4s2 electrons and one 3d electron.

2024年9月1日 · Ionic charge: When the atom loses or gains one or more electrons, the electric charge is generated (and an ion is formed). This electric charge generated on the ion is known as Ionic charge. When atoms gain electron/s, the negatively charged ion is formed, and when the atoms lose electron/s, the positively charged ion is formed.

Iron is a chemical element; it has the symbol Fe (from Latin ferrum 'iron') and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, forming much of Earth's outer and inner core.
