The hydrides of light metals are attractive for hydrogen storage because they can store a high weight percentage of hydrogen in a small volume example, NaAlH4 can release 5. NaAlH4 pos- sesses both covalent bonds, which hold polyatomic anions together, and ionic bonds. Which one is the least electronegative? Draw a Lewis structure for this ion. Q: Write nuclear equations for the following process: Krypton undergoes beta decay. A: The amount of stomach acid neutralised is calculated as,.
