Draw how a hydrogen atom becomes a positively charged ion?

Aluminum–lithium (al-li) alloys have been developed by the aircraft industry to reduce the weight and improve the performance of its aircraft. a commercial aircraft skin material having a density of 2.47 g/cm3 is desired. compute the concentration of li (in wt%) that is required.

What material does not melt at any temperature

How many moles of al3+ ions are in 1.25 moles of al2o3
