metallic state उदाहरण वाक्य

Europium becomes a superconductor when it is cooled below 1.8 K and compressed to above 80 GPa . This is because europium is divalent in the metallic state, and is converted into the trivalent state by the applied pressure.
In 1867, Roscoe began an elaborate investigation of vanadium and its compounds, and devised a process for preparing it pure in the metallic state, at the same time showing that the substance which had previously passed for the metal was contaminated with oxygen.
The energy of the 4f electron is nearly the same as that of the outer 5d and 6s electrons that are delocalised in the metallic state, and only a small amount of energy is required to change the relative occupancy of these electronic levels.
Care must be taken to avoid removing too much of the oxygen from the anode copper, as this will cause other impurities to change from their oxide to metallic states and they will remain in solid solution in the copper, reduce its conductivity and change its physical properties.
After postulating a direct correlation between electron concentration and crystal structure in beta-phase alloys, Hume-Rothery analyzed the trends in melting points, compressibilities and bond lengths as a function of group number in the periodic table in order to establish a system of valencies of the transition elements in the metallic state.

The helium abundance is relative to molecular hydrogen by number of molecules, and its mass fraction is, which is slightly lower than the Solar System's metallic state at depths of more than 10, 000 km, helium separates from it forming droplets which, being denser than the metallic hydrogen, descend towards the core.
This was first realised in 1995, when it was pointed out that a hypothetical metallic state of thorium that had the [ Rn ] 6d 2 7s 2 configuration with the 5f orbitals above the Fermi level should be hexagonal close packed like the group 4 elements titanium, zirconium, and hafnium, and not face-centered cubic as it actually is.
