A central idea in modern quantum mechanics is: (4 Points)

A wave character exhibited by all particles.

The acceleration of charged particles moving around a nucleus.

The opportunity to locate the position of an electron exactaly.

The continuous range of energies that electrons can have.

A wave character exhibited by all particles

Explanation:

The central idea in quantum mechanics is the paradox of wave-particle duality. In quantum mechanics, all particles are believed to also exhibit wavelike characters.

The electron is assumed to behave as a wave hence its position can not be precisely determined according the Heisenberg's uncertainty principle.

These are the underlying postulates that informed Erwin Schrödinger's wave mechanical model of the atom.

Hence, the basic postulate of quantum mechanics is that a wave character is exhibited by all particles.
