Why does the quantum mechanical description of many-electron atoms make it difficult to define a precise atomic radius?

Physics

Eddi Din [679]3 years ago

<span>Atoms and ions, at least within the quantum mechanical model do not have boundaries that are sharply defined at which the electron distribution becomes zero. When this occurs it can be very difficult to measure an atomic radius. The distance between the electrons in quantum mechanics is not set and would be problematic in determining the precise radius.</span>

Sati [7]
Alright, to begin with. The unit of Force is in Newtons. Meaning the first two options are out of the answers. Now in order to find the force. You will need to take the mass and multiply that by the acceleration. Which will give you 26.75 Newtons.

Molodets [167]

Answer:

the order of importance must be     b e a f c

Explanation:

Modern theories indicate that the moon was formed by the collision of a bad plant with the Earth during its initial cooling period, due to which part of the earth's material was volatilized and as a ring of remains that eventually consolidated in Moon.

Based on the aforementioned, let's analyze the statements in order of importance

b) True. Since the moon is material evaporated from Earth, its compassion is similar

e) True. If the moon is material volatilized from the earth it must train a finite receding speed

a) True. The solar system was full of small bodies in erratic orbits that wander between and with larger bodies

f) False. The moon's rotation and translation are equal has no relation to its formation phase

c) false. The amount of vaporized material on the moon is large

Therefore, the order of importance must be
