Question 18

Which ionisation process requires less energy than the one shown below?

Mg(g)→Mg+(g)+e− \text{Mg(g)} \rightarrow \text{Mg}^{+}(\text{g}) + \text{e}^{-} Mg(g)→Mg+(g)+e−
A
Be(g)→Be+(g)+e− \text{Be(g)} \rightarrow \text{Be}^{+}(\text{g}) + \text{e}^{-} Be(g)→Be+(g)+e−
B
Si(g)→Si+(g)+e− \text{Si(g)} \rightarrow \text{Si}^{+}(\text{g}) + \text{e}^{-} Si(g)→Si+(g)+e−
C
Al(g)→Al+(g)+e− \text{Al(g)} \rightarrow \text{Al}^{+}(\text{g}) + \text{e}^{-} Al(g)→Al+(g)+e−
D
Mg+(g)→Mg2+(g)+e− \text{Mg}^{+}(\text{g}) \rightarrow \text{Mg}^{2+}(\text{g}) + \text{e}^{-} Mg+(g)→Mg2+(g)+e−
