Question

Which of the following is
correct
O
IE2 of Cu< IE, of Zn
The oxidizing power of
halogens is Brı > CI, > F,
The ionization potential of
coinage metals is Au>Cu>Ag
IE, of He > IE, of Li​

Answer 1

The ionisation energy of the elements is expected to decrease down the group with an increase of distance between the valence electron and the nucleus and as well as because of the decrease in the effective nuclear charge.

So, the amount of energy required to ionize electron will be least for gold (atomic radius max). therefore the sequence regarding ionisation potential of coinage metal is:

Cu > Ag > Au

Hence, the correct option is A
