Ionic Bonds
Captions available
The idea
An ionic bond forms when a positively charged ion and a negatively charged ion attract and hold together by their opposite charges.
In practice
Sodium and chloride ions attract each other and pack into the crystal lattice of table salt.
Where people slip
An ionic bond holds ions together by charge attraction alone — no electron is shared between the two atoms.
