Iron has two valence electrons. The atomic number or iron is 26, and it has 26 electrons and 26 protons. The electron configuration of iron is 1s22s22p63s23p63d64s2 or 2, 8, 14, 2 electrons per shell, so an atom of iron has two electrons in the outermost shell.Continue Reading
When an atom of iron loses the two electrons from the last shell, it has a valency of +2, and when it loses two electrons from the 4s subshell and one electron from the 3d subshell, it has a valency of +3.
Iron is a transition metal and is placed in group eight or d-block and period four of the periodic table of elements. The melting point of iron is 2,800 degrees Fahrenheit.Learn more about Atoms & Molecules
Platinum has two valence electrons. The amount of electrons found on the outer shell of an element is known as the valence number. These electrons determine the number of bonds that the element can form.Full Answer >
Radium has two valence electrons. It is number 88 on the Periodic Table, meaning it has 88 protons and electrons. Therefore its electron configuration is 2, 8, 18, 32, 18, 8, 2, leaving 2 unpaired valence electrons in the outer shell.Full Answer >
Magnesium has two valence electrons. Valence electrons determine the chemical properties of an atom. The periodic table of elements is used to find the number of valence electrons in an element.Full Answer >
Beryllium has two valence electrons. Valence electrons are those electrons that are capable of participating in the formation of chemical bonds with other atoms. These chemical bonds occur through the sharing of these two electrons with other atoms.Full Answer >
