How many electrons in an atom can have the following quantum
gavmur [86]

The answer for the following question is explained.

<u><em>Therefore the  number of electrons present with the values n = 5, l = 2, m = -2, s = +1/2 is</em></u><u> </u><u><em>one(1).</em></u>

Explanation:

Here;

n represents the principal quantum number

l represents the Azimuthal quantum number

m represents magnetic quantum number

s represents spin quantum number

n = 5,

l = 2,

m = -2,

s = +1/2

Here, it implies 5d orbital.

In the  5d  orbital, 10 electrons.

As the magnetic quantum number is -2, and so it can have 1 electron.

<u><em>Therefore the  number of electrons present with the values n = 5, l = 2, m = -2, s = +1/2 is</em></u><u> </u><u><em>one(1)</em></u>

Why are some metals reactive than others?
Naddik [55]
<span> some elements have their outer electrons more tightly bound than others. Those who have less tightly bound electrons are more reactive. After this it gets more complex in explaining why they are bound with different strengths. </span>

When biological samples of unknown origins are discovered at a crime scene, what should investigators do?a. assume no pathogens
adoni [48]

Answer: assume pathogens are present and treat the samples accordingly

Explanation:

When investigators are unable to conclusively ascertain the source of a biological sample found at a crime scene, the correct thing to do is to treat it as if pathogens are present in it and handle it according to set rules on how to handle pathogens.

This is done to ensure that if a pathogen is indeed present, it would not cause a health emergency by infecting those who come in contact with the samples at the scene.
