The modern model of the atom describes electrons in a little less specific detail than earlier models did. Why is it that being less sure about the placement of electrons in an atom is actually an improvement over earlier models?
Electrons do not follow specific paths, so describing the area where an electron is likely to be is more scientifically accurate.
Electrons were thought to be negatively charged, but now scientists know that their charge depends on their energy level.
The modern model is based on mathematical equations, so the results become less clear when the decimals are rounded.
The position of electrons in atomic models has changed so much that it is better to have a less specific model than to be wrong again.
The correct answer is:
Electrons do not follow specific paths, so describing the area where an electron is likely to be is more scientifically accurate.
The modern model of the atom, known as the quantum mechanical model, is based on the principles of quantum mechanics. According to these principles, electrons do not follow specific, well-defined paths around the nucleus of an atom. Instead, their behavior is described by mathematical equations that give probabilities of finding an electron in different regions around the nucleus.
By acknowledging this probabilistic nature of electron behavior, the modern model provides a more accurate representation of the atom. It recognizes that electrons can exist in regions of space with varying probabilities and allows for a more comprehensive understanding of electron behavior and atomic structure.
