Web4 nov. 2024 · You may assume that the valences of the elements—the number of electrons with which an atom will bond or form—are those that can be derived by looking at the groups (columns) of the periodic table. While these are the most common valences, the real behavior of electrons is less simple. Web7 apr. 2024 · When selenium atom forms an ion it will? Selenium (Se) has an atomic number, and belongs to group 6A. So it will have 6 valence electrons. When two electrons are gained by selenium atom, it forms an anion having charge of -2. What ion is selenium most likely to form? Selenium has three common forms: Selenate, a water-soluble anion. pac 12 network on cox cable
