WebJan 8, 2024 · Explanation: Recall that an ion is just an atom that has gained or lost electrons. We know that metals tend to lose electrons, and non-metals tend to gain electrons. Transition elements can also be called transition metals, since all of them are metals. That must mean that they form cations by losing electrons. Answer link WebUNIT 3 When an element loses its valence electrons to form a cation, it assumes the electronic structure of the preceding noble gas. Ionic compounds are composed of both positive cations and negative anions and bear a neutral overall charge Metals and non-metals are joined by ionic bonds. Molecular compounds are usually formed when a …

WebThese non-metals will have 5, 6 or 7 electrons in the outer shell. ... For this reason, non-metals are more likely to gain electrons to form a full outer shell. WebAug 15, 2024 · It can be possible to predict whether an atom will form a cation or an anion based on its position on the periodic table. Halogens always form anions, alkali metals and alkaline earth metals always form cations. Most other metals form cations (e.g. iron, silver, nickel), whilst most other nonmetals typically form anions (e.g. oxygen, carbon ... northbridge hotel perth
