It decomposes to give BeO and CO 2. Hence, it is placed in the atmosphere of CO 2 which prevents decomposition. Be dissolves in alkali to form [Be(OH) 4] 2−. Be 2++4OH −→[Be(OH) 4] 2−. BeF 2 forms complexes with NaF in which Be goes with anion. BeF 2+2NaF→Na 2[BeF 4] 2−. midair crashesNettetThus, the stability of the decomposition product metal oxide decreases, as close packing is not possible.
