WebApr 14, 2024 · Iron-air batteries also tend to be heavier and larger than lithium-ion batteries that store equivalent energy. For batteries in phones, laptops, and cars, weight and volume are important features to keep in mind. However, this new technology could help accelerate uptake of large utility-scale batteries, where weight and volume are of less concern. Web6. How many electrons does iron have? Iron contains eight valence electrons. Because iron is a transition metal, electrons in its d subshells can be used as valence electrons. Valence electrons are electrons that exist outside of a noble-gas core in a transition metal. Iron has the electrical configuration 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 6. 7.
