Question

Choose the incorrect statement from the following:
a) Ionization energy of atom may be negative
b) Ionization energy of an ion may be negative
c) Ionization energy is inversely proportional to radius
d) Electron present in p orbital is in need of less energy for its removal as compared to electron present
in d orbital having the same principal quantum number​

Answer 1

Answer:

option C

The closer the electron to the nuclear the higher the attraction force, and thus the higher the energy required to overcome this attraction and remove the electron, *the smaller the radius the higher the ionization energy, and the bigger the radius the lower the energy need*
