Beryllium is resistive to complete oxidation. Why?
Answers
Explanation:
As little as 50 parts per million of beryllium alloyed with liquid magnesium leads to a significant increase in oxidation resistance and decrease ...
Oxidation states: 0, +1, +2 (an amphoteric oxide)
Electrical resistivity: 36 nΩ⋅m (at 20 °C)
Atomic number (Z): 4
Atomic radius: empirical: 112 pm
Answer:
A significant improvement in the oxidation of resistance and decrease in cost can be achieved by alloying liquid magnesium with beryllium at rate of 50 parts per million.
Explanation:
The only stable light metal that has a somewhat high melting point is beryllium. Under normal circumstances, beryllium quickly produces an adherent oxide surface film that shields the metal from additional air oxidation even if it is easily harmed by alkalies and non-oxidizing acids.
