Question

determine which statements are consistent with daltons atomic theory.
consistent
inconsistent
answer bank
all matter is made of atoms; atoms cannot be divided or destroyed.
atoms of one element cannot be converted into atoms of another element.
chemical reactions combine different elements in specific ratios to form compounds.
atoms of the same element have identical properties; atoms of different elements have different properties.
atoms can be divided or destroyed.
atoms of one element can be converted to atoms of another element.
atoms of the same element can have different properties.

Explanation:

Dalton's atomic theory has the following key postulates:

1. All matter is composed of indivisible atoms; atoms cannot be created, destroyed, or divided.
2. Atoms of the same element are identical in mass and properties; atoms of different elements have different masses and properties.
3. Atoms of different elements combine in fixed, whole - number ratios to form compounds.
4. Atoms of one element cannot be converted into atoms of another element in a chemical reaction.

Now let's analyze each statement:

• "All matter is made of atoms; atoms cannot be divided or destroyed." - Consistent with Dalton's theory (postulate 1).
• "Atoms of one element cannot be converted into atoms of another element." - Consistent with Dalton's theory (postulate 4).
• "Chemical reactions combine different elements in specific ratios to form compounds." - Consistent with Dalton's theory (postulate 3).
• "Atoms of the same element have identical properties; atoms of different elements have different properties." - Consistent with Dalton's theory (postulate 2).
• "Atoms can be divided or destroyed." - Inconsistent (opposite of postulate 1).
• "Atoms of one element can be converted to atoms of another element." - Inconsistent (opposite of postulate 4).
• "Atoms of the same element can have different properties." - Inconsistent (opposite of postulate 2).

Answer:

Consistent:

• All matter is made of atoms; atoms cannot be divided or destroyed.
• Atoms of one element cannot be converted into atoms of another element.
• Chemical reactions combine different elements in specific ratios to form compounds.
• Atoms of the same element have identical properties; atoms of different elements have different properties.

Inconsistent:

• Atoms can be divided or destroyed.
• Atoms of one element can be converted to atoms of another element.
• Atoms of the same element can have different properties.
