Web15 aug. 2024 · Ions are charged atoms or molecules. If a balanced atom loses one or more electrons, it will become a positively charged cation. If a balanced atom gains one or more electrons, it will become a negatively charged anion. What is a cation? A cation has more protons than electrons, consequently giving it a net positive charge. Web13 jul. 2024 · Beryllium gehört zur Familie der Seltenen Erdalkalimetalle. Berylliumionen „spenden“ bei der Bildung von Verbindungen (Ionen) 2 Valenzelektronen und werden dadurch zu einem positiv geladenen Ion. Wird Lithium Elektronen gewinnen oder verlieren, um eine volle äußere Schale zu erhalten?
