According to _ theory, atoms were the ultimate particles that cannot be divided further.
Correct answer: C. Dalton's
- A. Bohr's
- B. Rutherford's
- C. Dalton's
- D. Cannizzaro's
Explanation
OPTION A: Bohr's is incorrect as Niels Bohr's theory is related to the electronic structure of atoms, not the fundamental nature of atoms.OPTION B: Rutherford's is incorrect as Ernest Rutherford's theory is related to the structure of the nucleus, not the fundamental nature of atoms.OPTION C: All substances, according to Dalton's atomic theory, are made up of atoms, which are indivisible and indestructible building units.OPTION D: Cannizzaros is incorrect as Stanislao Cannizzaro's theory is related to the concept of chemical formulas and chemical reactions, not the fundamental nature of atoms.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
