Question

Define atomic orbital and nodal region

​

Answer 1

A nodal surface is a region of space in which the probability of finding an electron is zero. ... Also, all p orbitals have areas of zero electron probability in the xy,xz , or yz planes.

Answer 2

ATOMIC ORBITAL:-

An atomic orbital is a mathematical function describing the location and wave-like behavior of an electron in an atom.

NODAL REGION:-

Regions may be nodal, defined by the organization of activity about some central place (e.g., a town and its hinterland, or tributary area), or uniform, defined by the homogeneous distribution of some phenomena within it (e.g., a tropical rainforest).
