- Gallium was an element whose existence was predicted by Dmitry Ivanovich Mendeléyev in 1871 when he said that the then unknown element gallium should resemble aluminum in its properties.
- He therefore suggested the name eka-aluminium (symbol Ea).
- His predictions for the properties of gallium are remarkably close to reality.
- Gallium was discovered spectroscopically by de Boisbaudran when he found a zinc ore that displayed hitherto unknown spectral lines.
