Question

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.

Answer 1

Answer: A

Explanation: Just got it right.

Answer 2

A.

Step-by-step explanation:

Electrons don’t follow specific paths, so describing the area is more likely to be accurate. They orbit in clouds instead.
