why is the current model of the atom considered to be the most accurate?
a. the current model of the atom shows the exact location of all electrons in precise orbits, just like
planets.
b. the current model of the atom shows the probability of the electron location in orbitals of
different shapes.
c. the current model of the atom shows electrons randomly distributed in a sea of positive charge.
d. the current model of the atom shows the atom as a 3d structure instead of the flat atoms
proposed by the other scientists.
