Online Calculator of Chemical Bond

Chemical bond polarity is the concept that explains the property of sharing an electron between two elements. Covalent bond between the elements can be either polar or non-polar. This is determined with the concept of electro-negativity. If the electrons are shared equally between the atoms then its a non-polar covalent bond.

Rhenium improves the properties of tungsten. Tungsten-rhenium alloys are more ductile at low temperature, allowing them to be more easily machined. The high-temperature stability is also improved. The effect increases with the rhenium concentration, and therefore tungsten alloys are produced with up to 27% of Re, which is the solubility limit.
