  • The most expensive metal in the world

    Do you think the most expensive metal is gold? No! On earth there are more valuable metals. But we need to divide the value of metals that occur in nature, and metals - isotopes, which are obtained in special laboratories. Let’s look at natural metals first.



Most Popular

Electron Deficient Compounds

Compounds that contain at least one atom (other than H) that shares fewer than eight electrons.

Salt Bridge

A U-shaped tube containing electrolyte, which connects two half-cells of a voltaic cell.

Anode

In a cathode ray tube, the positive electrode. Electrode at which oxidation occurs.

Periodicity

Regular periodic variations of properties of elements with atomic number (and position in the periodic table).

Bubbles

Have you ever noticed that soap bubbles go up in winter and fall down in summer? The reason is that warm air is lighter than cold. And in winter the difference between the air temperature in the room (especially near the windows) and the one you exhale into the bubble is enough to overcome the heaviness of its shell.

Nuclear Binding Energy

Energy equivalent of the mass deficiency, energy released in the formation of an atom from the subatomic particles.

 

Nucleons

Particles comprising the nucleus, protons and neutrons.

Shielding Effect

Electrons in filled sets of s , p orbitals between the nucleus and outer shell electrons shield the outer shell electrons somewhat from the effect of protons in the nucleus, also called screening effect.

Downs Cell

Electrolytic cell for the commercial electrolysis of molten sodium chloride. For further information see Electrochemistry or Fuel Cells.

Outer Orbital Complex

Valence bond designation for a complex in which the metal ion utilizes d orbitals in the outermost (occupied) shell in hybridization.
