Just One Electron
by Anonymous · ⭐ 1 · 🍴 0
⚡ 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!
About this app
One Electron Apart is an interactive middle school science app designed to explore ions, chemical bonding, and precipitation reactions. Users manipulate electron counts to transform neutral atoms into cations or anions without altering proton numbers. The app also features guided activities for balancing ionic charges to construct chemical formulas and mixing solutions to observe precipitate formation.
Use cases
- Middle school students learning basic chemistry concepts and ion formation
- Science teachers demonstrating ionic bonding and charge cancellation in class
- Students practicing chemical formula writing and solubility rules interactively
Features
- Interactive electron addition and removal with real-time charge calculation
- Stoichiometric charge balancing activity to reveal subscripts in ionic formulas
- Solution mixing simulation to identify colored precipitates such as AgCl and PbI2
- Multi-tab guided interactive modules with instant feedback and audio controls
