The modern-day quantum model of the atom is better

Subject : Chemistry

Question:

The modern-day quantum model of the atom is better than John Dalton’s model because it

A) has set electron orbits.

B) has positive and negative particles in the nucleus.

C) can be represented in one dimension.

D) answers many questions about atoms.

Expert Verified Solution:

The correct answer is D)

Description: answers many questions about atoms. The modern quantum model of the atom provides a more accurate and detailed understanding of atomic structure compared to John Dalton’s model. Unlike Dalton’s model, which depicted atoms as solid, indivisible spheres, the quantum model incorporates principles of quantum mechanics, showing electrons in probabilistic orbitals rather than fixed paths. This model explains various atomic phenomena and addresses questions about electron behavior and energy levels, offering insights that Dalton’s simpler model could not.
