Which of the following statments is true regarding the wave mechanical model of the atom?
a. orbitals describe how an electron moves in an atom.
b. orbitals give a probability map of where it is likely to find an electron in an atom.
c. the wave mechanical model only works for hydrogen and no other atoms.
d. orbitals give us the exact location of an electron in an atom.
e. orbitals are just like orbits in the bohr model.

Orbitals give a probability map of where it is likely to find an electron in an atom.

Explanation:

Wave mechanical model of the atom suggests that an atom contains a nucleus which has positively charged protons and neutral neutrons.

The outer part of the atom is mostly empty.

The negatively charged electrons are located in outer orbitals.

The true statement is :

Orbitals give a probability map of where it is likely to find an electron in an atom.

a:

by the combination of an unlimited number of elements
