Any metal from group 2 (Mg, Ca, Sr, Ba)
electrons
it will lose 3 electrons
Indium is a metal and therefore it forms + ions. This means that it will lose electrons. Indium is a metal and therefore it forms + ions. This means that it will lose electrons.
An ionic bond.
Well, honey, let me break it down for you. When lead forms ions, it tends to lose electrons and become positively charged. So, in that case, lead loses electrons like it's going out of style. Hope that clears things up for you, darling.
An alkaline earth metal would typically lose two electrons to become stable. This would result in the metal forming a 2+ cation, as it will have the same electron configuration as the nearest noble gas.
Potassium will lose electrons when reacting with bromine. Potassium is a metal and tends to lose electrons to achieve a stable electron configuration, while bromine is a nonmetal that tends to gain electrons to achieve a stable electron configuration.
when it forms an ion it would gain two electrons, becoming negatively charged (2-)
Uranium loose electrons becoming a cation.
Gold would lose electrons to form an ionic bond. As a metal, gold has a tendency to donate electrons, resulting in a positively charged ion (cation). This electron loss allows gold to bond with nonmetals, which typically gain electrons to form negatively charged ions (anions). The electrostatic attraction between these oppositely charged ions forms the ionic bond.
Aluminum will lose 3 electrons to form Al3+ ion.
Iodine tends to gain one electron when it forms an ion.
