Formation of Ions

by Anonymous

Add and remove electrons to form ions, then combine them so charges cancel to zero and reveal chemical formulas and precipitates.

About this app

Formation of Ions is an interactive middle school chemistry app about how atoms become ions and how ions combine. Explore electron loss and gain for sodium, chloride, magnesium, and oxide ions, match ion quantities so the total charge is zero and reveal chemical formulas, then mix solution choices to identify precipitates such as AgCl, PbI₂, and BaSO₄.

Use cases

  • Middle school students learning ion formation
  • Science classes practicing ionic charges
  • Learners reviewing chemical formulas
  • Teachers demonstrating precipitation reactions

Features

  • Adjust electrons and observe ion charge changes
  • Practice forming Na⁺, Cl⁻, Mg²⁺, and O²⁻
  • Match cation and anion counts to balance total charge
  • Generate formulas including NaCl, MgCl₂, Na₂O, and Al₂O₃
  • Mix ion solutions to find white, yellow, or no precipitate
  • Progress through guided challenges with reset and next controls
