How many electrons in an atom can share the quantum numbers n = 4 and l = 3?
o-na [289]

Answer:

\boxed{\text{14}}

Explanation:

If l = 3, the electrons are in an f subshell.

The number of orbitals with a quantum number l is 2l + 1, so there

are 2×3 + 1 = 7 f orbitals.

Each orbital can hold two electrons, so the f subshell can hold 14 electrons.

\boxed{\textbf{14 electrons}} \text{ can share the quantum numbers n = 4 and l = 3.}

Why is glass brittle
WITCHER [35]
Glass doesn't contain planes of atoms that can slip past each other, so there is no way to relieve stress. It has many microscopic cracks that act as seeds for fracture. It’s molecular structure is composed of tetrahedral crystals so it ruptured easily under stress

Which of the following statements about the kinetic molecular theory are not correct?
Rashid [163]

Answer:

The false statement is: (C) The average kinetic energy of the molecules is not related to the absolute temperature

Explanation:

According to the Kinetic Theory of Gases, gases are composed of <u>small fast moving particles that are in constant random motion</u>. These gaseous particles are known as molecules.

It is assumed that the mass of all the gaseous molecules is the same and the <u><em>intermolecular interactions (attractive or repulsive) are negligible</em></u>.

Also, the <em><u>total volume of all the gaseous molecules is considered to be negligible as compared to the volume of the container.</u></em>

According to this theory, <em><u>average kinetic energy (K) of the gaseous particles is directly proportional to the absolute temperature (T) of the gas, </u></em>by the equation:

K = \frac{3}{2}k_{b}T

<em>Here, </em>k_{b}<em> is the Boltzmann constant</em>

<u>Therefore, the false statement about the kinetic molecular theory is (C)</u>
