likewise uses group theory in many ways. Abelian varieties. have been introduced above. The presence of the group operation yields additional information which makes these varieties particularly accessible. They also often serve as a test for new conjectures. [6] The one-dimensional case, namely . elliptic curves. is studied in particular detail.

The elements in Group 2 of the periodic table are called the alkaline earth elements. Like the elements in Group 1 (the alkali metals), the elements in Group 2 are chemically active and are never found in nature in the elemental state. Like all members of a group, or family, the elements in Group 2 share certain common characteristics.

Thermal stability of oxides in +2 and +4 oxidation states. Note that +4 oxidation state is more thermally stable than +2 for ALL the group IV elements EXCEPT lead. At lead, the situation reverses and the +2 is MORE thermally stable than the +4 oxidation state. This stability occurs for the aqueous ions as well.
