The discovery of hafnium, element number 72, provided a controversial episode in chemistry. G. Urbain, a French chemist, claimed in 1911 to have isolated an element number 72 from a sample of rare earth (elements 58-71) compounds. However, Niels Bohr believed that hafnium was more likely to be found along with zirconium than with the rare earths. D. Coster and G. von Hevesy, working in Bohr's laboratory in Copenhagen , showed in 1922 that element 72 was present in a sample of Norwegian zircon, an ore of zirconium. (The name hafnium comes from the Latin name for Copenhagen , Hafnia). Using their electron configurations, account for the fact that Zr and Hf form chlorides

Answer
Answer: A. He is determining physical properties that are sufficient to identify the metal.Chemical properties are properties which are determined by altering the chemical composition of a substance.
Physical properties are properties which are determined without altering the chemical composition of a substance.Physical properties such as density, electrical conductivity, and melting point are sufficient to identify a metal as these properties are independent of the amount of substance being examined.
These properties are known as intensive properties and are used to identify a substance by comparing the obtained values with standard values.Thanks (153)
