Chemistry......Is this true? ?

Question

A given electron orbital can occur in any geometric orientation in relation to the atom's nucleus, which explains the remarkable diversity that exists in types of chemical compounds.

Answer 1

No, the statement is not true.  The orbital can occur in any geometric orientation relative to the nucleus.  The electrons are far away from the nucleus, and it is approximately a point of uniform positive charge, so its orientation does not matter.  However, because the orbital cannot be too close to another electron orbital (due to electrostatic repulsion), the orbitals cannot be arranged arbitrarily.  Many elements only form compounds with a few geometries.
