Question

What was one main point of Dalton's atomic theory?

A. That atoms were made up of positive and negative charges

B. That atoms made up the smallest form of matter

C. That atoms changed as they formed compounds

D. That atoms had a nucleus at the center​

Answer 1

OPTION B.

Dalton's atomic theory highlighted that atoms are the smallest indivisible units of matter and that they combine in whole number ratios to form compounds.

Step-by-step explanation:

One main point of Dalton's atomic theory is that atoms made up the smallest form of matter. Dalton proposed that all matter is composed of these minute, indivisible particles, which he referred to as atoms, and these atoms cannot be subdivided, created, or destroyed. This concept also suggested that atoms of a given element are identical in size, mass, and other properties, whilst atoms of different elements differ. Additionally, Dalton's theory asserted that atoms of different elements can combine in whole number ratios to form chemical compounds and that during chemical reactions, atoms are rearranged but neither created nor destroyed.
