Question

13. Which of the following statements are not
correct:-
(1) The electron affinity of 'Si' is greater than
that of C
(2) BeO is amphoteric while B,O, is acidic
(3) The ionisation energy of 'TI' is less than that
of Al
Lanthenoid con
(4) The ionisation energy of elements of 'Cu'
group is less than that of the respective
elements of Zn-group​

Answer 1

Answer:

2 is wrong statement but other are truely correct

Answer 2

The ionisation energy of 'TI' is less than that of Al Lanthenoid con -That statement is note correct.

Explanation:

1. The electron affinity of silicon is greater than carbon because silicon has empty 3d orbital.-True
2. Beryllium oxide (BeO) is an amphoteric oxide of group II.Hydroxide aka (OH) ions are formed, so BaO is a basic oxide.- True
3. The ionisation energy of 'TI' is less than that of Al Lanthenoid con -False
4. The ionisation energy of zinc is bigger than copper's. That means that the outer electrons are being more firmly held. And yet some data shows that the zinc atom is bigger.- True
