How is an orbital is defined in the quantum mechanical model of the atom?
circular path traveled by a proton around an orbital
circular path traveled by an electron around an orbital
region of the most probable proton location
three-dimensional region in space around the nucleus where there is high probability of finding an electron
All the following statement about orbital are correct, EXCEPT
Two electrons can fit into one orbital.
Orbitals are the areas of space where an electron is likely to be found.
Orbitals can hold two electrons if they spin in the same direction.
It is designated for s, p, d and f orbitals.
