Parts of dalton’s atomic theory were disproved. do you think that this should be taken as a criticism of dalton as a scientist? use a description of what you think a good scientist is to support your answer

No, i don't believe so.
Making false interpretation from research results is extremely common among scientists,  but every mistake that scientists made over a period of time, opened up a new path for future scientist in perfecting the knowledge.
I'm sure dalton himself always provide rooms for other scientists to review and evaluate his theory and other scientists also realize that without dalton, knowledge in the chemical field wouldn't be able to move forward.
