Question

all of the following are assumptions presented by daltons atomic theory except that
a) all atoms of
different
elements are alike
in size, shape, and
weight.

b) atoms combine
with other atoms.

Explanation:

Dalton's atomic theory states that atoms of the same element are identical in size, mass, and other properties, while atoms of different elements are different. Option A claims all atoms of different elements are alike, which contradicts Dalton's theory. Option B (atoms combine with other atoms) is a correct assumption of Dalton's theory as atoms form compounds by combining in whole - number ratios.

Answer:

A) all atoms of different elements are alike in size, shape, and weight.
