¿cuál de los siguientes no forma parte de la teoría atómica de dalton? (6a)
all matter is composed of indivisible atoms.
atoms of the same element can be different.
compounds form when atoms combine in whole number ratios.
a chemical reaction involves rearrangement of atoms.

Explanation:

Dalton's atomic theory states that all matter is made of indivisible atoms (a), atoms of the same element are identical (so b is incorrect as it says atoms of the same element can be different), and compounds form when atoms combine in whole - number ratios (c). A chemical reaction involving rearrangement of atoms (d) is also in line with chemical change concepts related to atomic theory.

Answer:

B. Atoms of the same element can be different.
