The answer is 3.
Fe -> Fe3+ + 3e
The H+ ion has no electrons.
When iron loses three electrons it becomes ferric (Fe3+) ion
Fe3- represents an ion of iron with a 3- charge. The symbol "Fe" refers to the element iron, and the superscript "-3" indicates that the ion carries a negative charge of 3. The 3- charge means that the ion has gained three electrons to achieve a stable configuration.
Fe3+ is the chemical symbol for iron (III) ion, which is a positively charged ion of iron. It means that the iron atom has lost three electrons, resulting in a charge of +3. Iron (III) ions are commonly found in compounds and minerals.
Brownish green
it should lose 3 electrons
5 unpaired electrons There are 5 unpaired electrons in the Fe3+ ion. The reason for this is that Iron has the electron configuration Ar3d5.
There are 5 unpaired electrons in Fe^3+ in its ground state.
The formula for ferric ion is Fe3+. It is the ion form of iron when it has lost three electrons.
The H+ ion has no electrons.
When iron loses three electrons it becomes ferric (Fe3+) ion
A Co3+ ion has lost three electrons from its neutral state, so it has 23 electrons.
There are 4 unpaired electrons in the ground state electron configuration of an Fe atom. These 4 unpaired electrons are in the 3d subshell.
Fe3- represents an ion of iron with a 3- charge. The symbol "Fe" refers to the element iron, and the superscript "-3" indicates that the ion carries a negative charge of 3. The 3- charge means that the ion has gained three electrons to achieve a stable configuration.
An Mg2+ ion has lost two electrons, resulting in a total of 10 electrons. Magnesium normally has 12 electrons but when it forms a 2+ ion, it loses two electrons.
The charge of the ion is 2+.This would be represented as Fe2+.
Fe3+ is the chemical symbol for iron (III) ion, which is a positively charged ion of iron. It means that the iron atom has lost three electrons, resulting in a charge of +3. Iron (III) ions are commonly found in compounds and minerals.
