Answer:

The electron spin can only take place in opposite directions.

Explanation:

The angular momentum of a quantum number deals with the shape of the atomic orbital. Each orbital has a specific shape. In addition, the electrons have specific spin directions. let's say a quantum number, m is having two three shells. It means that:

number of shells, n = 3.

The level will be 3

the possible spins will be 0, 1, 2.

This takes place in the negative direction as well to give:

-2 , -1, 0, 1, 2

Thus, 3,2,-3,+1/2 cannot be a quantum number as it does not have a equal and opposite spin.

L = an integer from 0 to n-1 
<span>mL = an integer from -L to +L </span>
<span>ms = + or - 1/2 </span>

<span>the format is (n, L, mL, ms) </span>

<span>so your </span>
<span>n = 3... this is OK </span>
<span>L = 2.. also OK.. if n=3, L can = 0, 1, or 2 </span>
<span>mL = -3 is NOT ok... if L=2.. mL can only be -2, -1, 0, +1, or +2 </span>
<span>ms = +1/2 and that is ok

Hope this helps!</span>

How does a Camel prevent the loss of water from their body?​
Schach [20]

Camels lose less water through their urine and feces than many other mammals. Their kidneys concentrate water heavily, leading to salty urine. The intestines also reabsorb water from intestinal material as it is digested, so dry feces are produced.

For metals, reactivity _____ as you go from _____ in a period.
ki77a [65]

Reactivity - Reactivity refers to how likely or vigorously an atom is to react with other substances. This is usually determined by how easily electrons can be removed (ionization energy) and how badly they want to take other atom's electrons (electronegativity) because it is the transfer/interaction of electrons that is the basis of chemical reactions.  

Metals  

Period - reactivity decreases as you go from left to right across a period.  

Group - reactivity increases as you go down a group  

Why? The farther to the left and down the periodic chart you go, the easier it is for electrons to be given or taken away, resulting in higher reactivity.  

Non-metals  

Period - reactivity increases as you go from the left to the right across a period.  

Group - reactivity decreases as you go down the group.  

Why? The farther right and up you go on the periodic table, the higher the electronegativity, resulting in a more vigorous exchange of electron
