what new characteristic did john dalton add to the model of the atom?\no an atom is a round, solid mass.\no an atom has a massive, positive center.\no an atom is made up of smaller particles.\no an atom can join with other kinds of atoms.
Answer
Answer:
D. An atom can join with other kinds of atoms.
Brief Explanations:
John Dalton proposed that atoms of different elements can combine in simple whole - number ratios to form compounds, meaning atoms can join with other kinds of atoms. His model described atoms as round, solid masses (but this wasn't a new characteristic compared to earlier ideas), and the concepts of a massive positive center and being made up of smaller particles came later with other models.
