Question
The probability density plots of 1$$s$$ and 2$$s$$ atomic orbitals are given in figures.
The probability density plots of 1$$s$$ and 2$$s$$ atomic orbitals are given in figures.
The density of dots in a region represents the probability density of finding electrons in the region.
On the basis of the above diagram, which of the following statements is incorrect ?
A.
$$1s$$ and $$2s$$ orbitals are spherical in shape.
B.
The probability of finding the electron is maximum near the nucleus.
C.
The probability of finding the electron at a given distance is equal in all directions.
D.
The probability density of electrons for $$2s$$ orbital decreases uniformly as distance from the nucleus increases.
Answer :
The probability density of electrons for $$2s$$ orbital decreases uniformly as distance from the nucleus increases.
Solution :
For $$1s$$ orbital, the probability density is maximum at the nucleus and it decreases sharply as we move away from it. On the other hand, for $$2s$$ orbital, the probability density first decreases sharply to zero and again starts increasing.
For $$1s$$ orbital, the probability density is maximum at the nucleus and it decreases sharply as we move away from it. On the other hand, for $$2s$$ orbital, the probability density first decreases sharply to zero and again starts increasing.
