Question

1. the electron cloud model describes the ____ of electrons in an atom. charge likely locations number precise locations

Explanation:

The electron cloud model is a modern model of the atom. In this model, electrons are not in fixed orbits. Instead, it shows the regions (likely locations) where electrons are most likely to be found around the nucleus. The charge of an electron is always negative (- 1.6×10⁻¹⁹ C), and this is not what the electron - cloud model specifically describes. The number of electrons in an atom is given by the atomic number (for neutral atoms, equal to the number of protons), and the model is not about counting electrons. Also, due to the Heisenberg uncertainty principle, we cannot know the precise locations of electrons simultaneously with their momenta, so the model does not show precise locations.

Answer:

B. likely locations
