How are the ions formed by transition metals

Web14 de ago. de 2024 · Ions are formed when atoms lose or gain electrons in order to fulfill the octet rule and have full outer valence electron shells. When they lose electrons, they become positively charged and are named cations. When they gain electrons, they are negatively charged and are named anions. What groups form ions? WebOne of the remarkable properties of transition elements is their colour. It has been seen that most of the transition metal compounds show particular colours. This means that some visible spectra are absorbed by these elements from white light as it passes through a sample of transition metals. When transition elements are not bonded to ...
