Question
All atoms of the same element are identical in __________ and ______.
- Volume, mass
- Shape, size
- Mass, size
- Volume, properties
Hint:
Dalton's theory proposed the idea of atoms and their properties.
The correct answer is: Mass, size
- All atoms of the same element are identical in mass and size.
- According to Dalton's atomic theory, atoms are the smallest particle known in this universe. They are indivisible which suggests that they cannot be divided any further.
- Dalton also suggested that the atoms of the same element are the same in mass and even in their size. Though this theory was later disproved because there are certain elements that have the same atomic number but different atomic masses or some that exist in more than one form.
The elements with the same atomic number and different atomic mass are known as isotopes.
