2Be + C → Be 2 C CaO + 3C → CaC 2 + CO (at 2500 °C in furnace) CaC 2 + 2H 2 O → Ca(OH) 2 + C 2 H 2 Mg 2 C 3 + 4H 2 O → 2Mg(OH) 2 + C 3 H 4. Reaction with nitrogen. Only Be and Mg form nitrides directly. 3Be + N 2 → Be 3 N 2 3Mg + N 2 → Mg 3 N 2. Reaction with hydrogen. Alkaline earth metals react with hydrogen to generate saline ...
Its melting point of 1173 °C is significantly higher than that of plutonium (639 °C) and europium (826 °C), but lower than for curium (1340 °C). [ 45 ] [ 47 ] At ambient conditions, americium is present in its most stable α form which has a hexagonal crystal symmetry , and a space group P6 3 /mmc with cell parameters a = 346.8 pm and c ...
The high-energy beta particles from 32 P penetrate skin and corneas and any 32 P ingested, inhaled, or absorbed is readily incorporated into bone and nucleic acids. For these reasons, personnel working with 32 P is required to wear lab coats, disposable gloves, and safety glasses, and avoid working directly over open containers.
