Since oxygen is not a metal, its ions are not normally written with Roman numbers suffixed, but an oxide ion, with formula O-2, contains 10 electrons.
Many Transition Metals can have different numbers of valence electrons. The "II" means it has 2 valence electrons.Thanks & Regards,Shoaib Khan - SRKMob: +91-9534330837Email: shoaibrazakhan@gmail.com
Iron II, also known as ferrous ion, has 26 protons. The Roman numeral II indicates that it has a +2 charge, which is achieved by losing two electrons from the neutral iron atom.
The oxidizing agent in the conversion of copper metal to copper II ion is the other half of the redox reaction. In this case, it would be the substance that gains electrons, which is the oxidizing agent. In this reaction, the oxidizing agent would be whatever substance oxidizes the copper metal (loses electrons) to form copper II ion. This is typically noted as the substance that has "reduced" the other reactant.
Polonium (Po) typically forms a 2+ cation, known as the polonium(II) ion. This ion has a charge of +2 due to the loss of two electrons from a neutral polonium atom.
The name of the Mn2+ ion is manganese(II) ion.
When copper combines with oxygen to form copper (II) oxide, the charge of the copper ion is +2. This is because in copper (II) oxide, each copper ion has lost two electrons to oxygen atoms, resulting in a +2 charge.
the formula for manganese II ion is Mn 2+ .it is a positively charged ion
2 electrons = ferrous or iron(II) or Fe+23 electrons = ferric or iron(III) or Fe+3

Iron II, also known as ferrous ion, has 26 protons. The Roman numeral II indicates that it has a +2 charge, which is achieved by losing two electrons from the neutral iron atom.
The formula for ferric ion is Fe3+. It is the ion form of iron when it has lost three electrons.
two elements with ions with a 2 plus charge are Sulfurand Oxygen
Lead II ion has a 2+ charge and consists of a lead atom that has lost two electrons. It is typically found in compounds with a variety of other elements due to its tendency to form stable chemical bonds. Lead II ion can be toxic to humans if ingested or inhaled in large amounts.
The roman numeral II in the name Iron II indicates that the cation has a +2 charge. This means that the iron ion has lost two electrons, resulting in a positive charge.

Because the element magnesium is in the Group II category, it is has two electrons in its outer shell, donating them to leave it with a 2+ charge. Therefore, when it is in the ionized form, it is Mg2+
The correct name for this compound would be iron(III) sulfide. Iron (Fe) has an atomic number of 26, so it contains 26 electrons in its neutral state. When it forms a +3 ion by losing 3 electrons, it now has 23 electrons. Sulfur (S) typically forms a -2 ion by gaining 2 electrons, bringing the total to 24 electrons when combined with iron(III).
