Question

Choose one: Orbital shapes have no physical meaning, but we draw different shapes to distinguish orbitals from each other. The shape of an orbital encompasses all the possible locations of an electron around a nucleus. None of the other statements correctly explains why orbitals have the shapes they do. The shape of an orbital describes a surface that encompasses about 90% of the probability of finding an electron around a nucleus. Orbital shapes describe the path traveled by an electron as it moves around the nucleus.

Answer 1

Answer: The shape of an orbital describes a surface that encompasses about 90% of the probability of finding an electron around a nucleus.

Explanation:

An orbital is described as a region in Space around which there is a high probability of finding an electron.

Orbitals possess various shapes. The shape of an orbital describes the region around the nucleus within which an electron in a given energy level may be found with a greater probability.
