Question 12

Which ionisation requires less energy than the process shown below?

Mg(g)→Mg+(g)+e− \text{Mg(g)} \rightarrow \text{Mg}^{+}(\text{g}) + e^{-} Mg(g)→Mg+(g)+e−
A

Be(g)→Be+(g)+e−\text{Be(g)} \rightarrow \text{Be}^{+}(\text{g}) + e^{-}Be(g)→Be+(g)+e−

B

Si(g)→Si+(g)+e−\text{Si(g)} \rightarrow \text{Si}^{+}(\text{g}) + e^{-}Si(g)→Si+(g)+e−

C

Al(g)→Al+(g)+e−\text{Al(g)} \rightarrow \text{Al}^{+}(\text{g}) + e^{-}Al(g)→Al+(g)+e−

D

Mg+(g)→Mg2+(g)+e−\text{Mg}^{+}(\text{g}) \rightarrow \text{Mg}^{2+}(\text{g}) + e^{-}Mg+(g)→Mg2+(g)+e−
