Question

Check the statements that are a part of the Early Atomic Theory.

A. Scientists believe that the atom is made up of elements.
B. Atoms combine in whole number ratios to form compounds.
C. Atoms cannot be created or destroyed during a chemical reaction.
D. DONE

Answer 1

The correct statements from Early Atomic Theory are that atoms combine in whole number ratios to form compounds (B) and that atoms cannot be created or destroyed during a chemical reaction (C).

Step-by-step explanation:

Early Atomic Theory Statements

Early Atomic Theory includes several key postulates that were first proposed by John Dalton and other scientists. Among them, the statements that reflect the early ideas are:

Atoms combine in whole number ratios to form compounds.

Atoms cannot be created or destroyed during a chemical reaction, which is known as the law of conservation of mass.

To break down the provided statements:

B. Atoms combine in whole number ratios to form compounds. - Correct

C. Atoms cannot be created or destroyed during a chemical reaction. - Correct

Statement A is not accurate within the context of Early Atomic Theory; rather, the theory posits that elements are made up of atoms, not the other way around. Dalton's theory has been updated in light of modern scientific discoveries, but these two principles still demonstrate foundational ideas that were correct at the time.
