WebThe chemistry of the two heaviest group 5 metals (Nb and Ta) is dominated by the +5 oxidation state. The chemistry of the lightest element (V) is dominated by lower oxidation … In chemistry, a transition metal (or transition element) is a chemical element in the d-block of the periodic table (groups 3 to 12), though the elements of group 12 (and less often group 3) are sometimes excluded. The lanthanide and actinide elements (the f-block) are called inner transition metals and are sometimes considered to be transition metals as well.

WebIn keeping with their highly electropositive character, the group 3 metals react with water to produce the metal hydroxide and hydrogen gas: (23.4.1) 2 M ( s) + 6 H 2 O ( l) → 2 M ( O H) 3 ( s) + 3 H 2 ( g) The chemistry of the group 3 metals is almost exclusively that of the M 3+ ion; the elements are powerful reductants. regs catering banbury
