The correct answer is 'A'.
Explicación
## Step 1The problem is asking us to identify the reason why the modern model of the atom describes electrons in less detail than the older, cartoon models. The options provided are:1. Electrons do not follow specific paths, so describing the area where an electron is more likely to be found is more accurate.2. Electrons were thought to be negatively charged, but now scientists know that their charge depends on their energy level.3. The modern model is based on mathematical equations, so the results become less clear when the decimals are rounded.4. The position of electrons in atomic models has changed so much that they are now considered to be in a cloud rather than a fixed orbit.## Step 2The first option is the correct answer. In the modern model of the atom, electrons are not described as following specific paths, but rather as being in a cloud or an area where they are more likely to be found. This is because electrons do not have fixed orbits, but rather exist in regions of space called electron clouds or orbitals. This is a more accurate description of the behavior of electrons than the older, cartoon models, which depicted electrons as following specific paths.## Step 3The other options are incorrect. Electrons are indeed negatively charged, and their charge does not depend on their energy level. The modern model is not based on mathematical equations, and the position of electrons in atomic models has not changed so much that they are now considered to be in a cloud rather than a fixed orbit.
