Correct Answer: Cation -A
Given that both the cations, cation-A and cation -B have the same concentrations.
Charge on cation-A is +3, while charge on cation- B is +1. Cations with higher charge can easily substitute those present on the clay minerals. Cations with higher charge have a greater affinity for the negatively charged sites present on the clay mineral. So, cation -A with a charge of +3 is more likely to occupy the anionic sites on the clay mineral.
Answer is: Filtering a mixture will separate it into substances.
Pure substance is made of only one type of atom (element) or only one type of molecule, it has definite and constant composition with distinct chemical properties. Pure substances can be separated chemically, not physically, that is difference between pure substances and mixtures.
Filtration is use for separation of heterogenous mixture, for example, sand and water.
The magnitude of the orbital angular momentum of the electron is doubled when the radius of the electron orbit increases by a factor of four.
<h3>
What is orbital angular momentum?</h3>
The orbital angular momentum is the sum of angular momenta of all electrons, it is the rotational analog of the linear momentum.
The formula of angular momentum

Thus, the magnitude of the orbital angular momentum of the electron is doubled when the radius of the electron orbit increases by a factor of four.

Answer:
Chlorine has 17 total electrons with electron configuration 1s^2 2s^2 2p^6 3s^2 3p^5.
What are the first two quantum numbers for the six electrons in the 2p subshell?
Explanation:
The principal quantum number represents the shell number in which the electron is present.
It is represented with "n".
The next quantum number is the azimuthal quantum number.
It represents the shape of the orbital.
It has values from 0 to (n-1).
Its value depends on the principal quantum number.
Chlorine has 17 total electrons with electron configuration 1s^2 2s^2 2p^6 3s^2 3p^5.
For the six elecetrons in 2p subshell:
The first two quantum number values are the same and their values are:
n=2 , l=1.
