Study Notes

Lattice Structure of Transition Metals

  • Transition metals typically have a close-packed crystal lattice structure, commonly found in face-centered cubic (FCC) or hexagonal close-packed (HCP) arrangements.
  • The d-orbitals allow for a variety of bonding and coordination geometries, contributing to their unique physical and chemical properties.

Oxidation States of Transition Metals

  • Transition metals exhibit multiple oxidation states, with the most common being +2 and +3.
  • The availability of d-electrons facilitates a range of oxidation states, crucial in redox reactions and catalysis.

Formation of Sodium Chromate (Na2CrO4)

  • The formula for sodium chromate involves the reaction of sodium hydroxide with chromic acid, yielding Na2CrO4 as a product.

Formation of Potassium Dichromate (K2Cr2O7)

  • Potassium dichromate is formed from the oxidation of chromium compounds in the presence of potassium hydroxide, resulting in the formula K2Cr2O7.

Chemical Symbol for Actinium

  • The chemical symbol for Actinium is Ac.

Oxidation States of Actinoids

  • Actinoids exhibit a range of oxidation states, primarily +3 and +4, but can extend up to +6 in specific compounds.
  • The variability in oxidation states arises from the f-orbitals of the actinoids, similar to the d-orbitals in transition metals.
