Final answer:
Dalton's Atomic Theory proposed several postulates that are still accepted in the modern atomic theory, including the existence of atoms, the identical nature of atoms within an element, and the combination of atoms to form compounds.
Step-by-step explanation:
Dalton's Atomic Theory proposed several postulates that are still accepted in the modern atomic theory. These include:
- Elements are composed of tiny indivisible particles called atoms.
- All atoms of the same element are identical in mass and properties.
- Atoms can combine in simple whole number ratios to form compounds.
These postulates have been modified and expanded upon in the modern atomic theory, which includes concepts such as subatomic particles, isotopes, and electron configurations.
