Question

which statements of daltons theory explain why chemical formulas are always written with whole - number values? (select all that apply.) atoms of different elements have different masses and sizes. atoms combine to form compounds in simple numerical ratios, such as one to one, one to two, etc. atoms of the same element are alike in mass and size. atoms of two elements may combine in different ratios to form more than one compound.

Explanation:

Dalton's theory states that atoms combine to form compounds in simple whole - number ratios. This is why chemical formulas have whole - number values. The statement about atoms combining in simple numerical ratios directly relates to whole - number coefficients in chemical formulas. Other statements do not address the reason for whole - number values in formulas.

Answer:

Atoms combine to form compounds in simple numerical ratios, such as one to one, one to two, etc.
