Chemical Bonding Lab

Virtual Lab

Enter the bonding playground: combine atom cards, compare ionic and covalent rules, and let Master Alchem point out the valence pattern.

Prototype

Bonding playground

Choose a compound to compare electron transfer, electron sharing, and valence-shell reasoning. Drag-and-drop bonding is reserved for a later build.

Sodium chloride

Ionic bonding

Sodium tends to lose one valence electron and chlorine tends to gain one, producing Na+ and Cl- held by electrostatic attraction.

Metal + nonmetal

Electron transfer

Crystal lattice

High melting point

Ask: are electrons transferred or shared? Then connect that answer to formula, charge, structure, and properties.
