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
nasty-shy [4]

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.

This experiment is more about understanding the colligative properties of a solution rather than the determination of the molar
Afina-wow [57]
Colligative properties are properties of solutions that result from adding solute to a solvent and that depend on the concentration of solute particles, but independent of the identity of the solute molecules or ions. The four colligative properties are boiling point elevation, freezing point depression, osmotic pressure, and vapor pressure lowering.
