Question

10.
Which of the following is/are true information (s)?
a) 3s orbital is spherically symmetrical with two nodes
b) dx^2-y^2 orbitals has lobes of electron density in XY - plane along X- and Y -axis
c) the radial probability curve of ls, 3p and 5d have one, two and three regions of maximum
probability
d) 3dz^2 has zero electron density in XY - plane​

Answer 1

Answer:

second one what you have mantioned

Answer 2

B is true.

Three radial nodes make up a 3s orbital. A node is a site where the spatial probability of electrons is zero. The number of radial nodes grows by n-1 in proportion to the principle coefficient. The s orbital boundary surface diagram resembles a spherical with the nucleoplasm at its core, which can be visualised as a circle in 2 components. As a result, s-orbitals are spherically symmetric, with the chance of locating the electron at a given distance being the same in all directions.
