The current atomic model has a. A. clear and exact placement for every electron around the nucleus of an atom. B. clear and distinct border surrounding the nucleus of an atom where electrons are located. C. predicted area surrounding the nucleus where the electron could be located.

The Bohr model used to be used but it signifies that electrons stay stationary. The current model uses electron clouds in order to predict the location of an electron within an atom.

Additionally, we can predict the location of an electron, but we cannot exactly pinpoint it. So, the current atomic model cannot have a clear and exact placement for every electron around the nucleus of an atom. It also cannot have a clear and distinct border surrounding the nucleus of an atom where electrons are located.

Therefore, the current atomic model has a predicted area surrounding the nucleus where the electron could be located.
