Answer:

Since electrons cannot have the same set of quantum numbers, a maximum of two can be in the n = 1 level, and a third electron must reside in the higher-energy n = 2 level. If there are two electrons in the n = 1 level, their spins must be in opposite directions.

Which of the following is true concerning ψ²? A) ψ² describes the probability of finding an electron in space. B) ψ² describes t
Ilia_Sergeevich [38]

Answer:

A) ψ² describes the probability of finding an electron in space.

Explanation:

The Austrian physicist Erwin Schrödinger formulated an equation that describes the behavior and energies of submicroscopic particles in general.

The Schrödinger equation i<u>ncorporates both particle behavior</u>, in terms of <u>mass m</u>, and wave behavior, in terms of a <u><em>wave function ψ</em></u>, which depends on the location in space of the system (such as an electron in an atom).

The probability of finding the electron in a certain region in space is proportional to the square of the wave function, ψ². According to wave theory, the intensity of light is proportional to the square of the amplitude of the wave, or ψ². <u>The most likely place to find a photon is</u> where the intensity is greatest, that is, <u>where the value of ψ² is greatest</u>. A similar argument associates ψ² with the likelihood of finding an electron in regions surrounding the nucleus.

1pt Which particle is a neutron most equal to in mass?
My name is Ann [436]

Answer:

c. a proton

Explanation:

A neutron is most equal in mass to a proton.

A neutron is a subatomic particle without any charges on them.

A proton is a subatomic particle with a positive charge.

  • the mass of a proton and neutron are the most similar in an atom.
  • the mass of a proton is 1.67 x 10⁻²⁷kg
  • So also is the mass of a neutron
  • the mass of an electron is 9.11 x 10⁻³¹kg
