Scandium reactivity
WebAs shown in Table 23.4. 1, the observed trends in the properties of the group 3 elements are similar to those of groups 1 and 2. Due to their ns 2 (n − 1)d 1 valence electron configurations, the chemistry of all four elements is dominated by the +3 oxidation state formed by losing all three valence electrons.
