Ionic electron transfer
A metal atom gives electrons to a non-metal atom; the ions attract and form an ionic lattice.
Open the interactive simulation →How to use this simulation
- The Reaction Lab opens with Na and Cl in the workspace. Press play.
- Watch the outer electron move from Na to Cl.
- Open “Analysis” to read the ion configurations and the formula from charge balance.
- Try other pairs from the “Try an experiment” list, such as Mg + O.
What to notice
- Both ions end up with a noble-gas configuration.
- The formula balances charges: Na⁺Cl⁻ but Mg²⁺O²⁻ and Mg²⁺(Cl⁻)₂.
