Explanation:
mass = desity × volume
volume = mass/density...
i believe thats right...
btw u means Physics formulae only..lol
Answer:
One mole of U238 ( 6.022 X 10^23 atoms) is 238 grams; one mole of U235 is 235 grams. The difference in molecular weight between a mole of U235 and U238 is 3 grams, the secret to enriching uranium.
Explanation:
It is true that metallic bonds are responsible for many properties of metals such as conductivity.
Metallic bond is a type of chemical bond.
Metallic bond is formed between electrons and positively charged metal ions.
Substances with metallic bond conduct an electric current in liquid and solid state, because they have mobile electrons.
Most metals (for example sodium, calcium, iron, silver) have strong metallic bond, because strong electrostatic attractive force between valence electrons (metals usually have low ionization energy and lose electrons easy) and positively charged metal ions.
Metallic bond increace electrical and thermal conductivity.
