Scandium - Element information, properties and uses

In 1869, Mendeleev noticed that there was a gap in atomic weights between calcium (40) and titanium (48) and predicted there was an undiscovered element of intermediate atomic weight. He forecast that its oxide would be X 2 O 3. It was discovered as scandium in 1879, by Lars Frederik Nilson of the University of Uppsala, Sweden.
