ancient atomic models described the atom as a solid sphere with no charge. in the 1800s and 1900s, scientists discovered subatomic particles with charges inside the atom. which statement most likely explains why the early models did not include the subatomic particles? a atoms changed over time to develop subatomic particles. b not all atoms contain subatomic particles. c subatomic particles move and cannot be counted. d subatomic particles could not be detected with the technology available.

Explanation:

Early atomic models were limited by the technology of the time. Subatomic particles were not detected because the available technology was not sensitive enough to identify them.
