Just One Electron

⚡ What happens when an atom loses an electron? With one less electron than protons, a +1 charge remains—that's an ion! Add or remove electrons to make Na⁺, Cl⁻, Mg²⁺, and O²⁻ yourself. Remember, proton numbers never change, or it becomes a totally different element! 🔗 Next is matching pairs! Cations and anions only combine so their total charge equals 0. One 2+ needs two 1−, and two 3+ need three 2−. Get it right to reveal chemical formulas like NaCl, MgCl₂, Na₂O, and Al₂O₃—those subscripts were the atom counts all along! 🧪 Last is the lab! Mix solutions to see which pairs turn cloudy and which stay clear. Silver and chloride form white precipitates, lead and iodide turn yellow, but nitrate never forms a precipitate with anything! Made with code—remix it to add your own ions!
