Give the value of the quantum number ℓ, if one exists, for a hydrogen atom whose orbital angular momentum has a magnitude of 6√(
MakcuM [25]

Answer:

For this angular momentum, no quantum number exist

Explanation:

From the question we are told that

   The magnitude of the angular momentum is  L  = 6\sqrt{\frac{h}{2 \pi} }

The generally formula for Orbital angular momentum is mathematically represented as

           L  = \sqrt{(l * (l + 1)) } *  \frac{h}{2 \pi}

Where l is the quantum number

now  

We can look at the given angular momentum in this form as

      L  = 6\sqrt{\frac{h}{2 \pi} }    =  \sqrt{36}  * \sqrt{\frac{h}{2 \pi}} }

comparing this equation to the generally equation for Orbital angular momentum

     We see that there is no quantum number that would satisfy this equation

In general, which two factors determine the overall temperature of earth's atmosphere?
ehidna [41]
These two factors are:
*radiation coming into the Earth's atmosphere
*radiation going out the Earth's atmosphere

These two factors could be lumped into one natural phenomenon called the greenhouse effect. The Earth's atmosphere is a very unique characteristic in the solar system because it makes the planet livable. Without the atmosphere's work, the day would be too hot and the night would be too cold. The trapping of radiation, hence heat, keeps the overall temperature of the Earth.

An average, how many eggs does a female release each<br> cycle?
bagirrra123 [75]

Answer:

At birth, there are approximately 1 million eggs; and by the time of puberty, only about 300,000 remain. Of these, only 300 to 400 will be ovulated during a woman's reproductive lifetime. Fertility can drop as a woman ages due to decreasing number and quality of the remaining eggs.
