How many electrons have an azimuthal quantum number (l) with the value +1 in a fluorine atom?

a. zero
b. six
c. two
d. five
e. four

5

Explanation:

F:1s²2s²2p₋₁²2p₀²2p₊₁¹

QN's for each of nine Fluorine e⁻'s => values in 'bold' are the orbital (or, azimuthal) QN's with values = +1.

           n    l     m    mₓ

1s¹        1     0    0   +1/2

1s²       1     0    0   -1/2

2s¹       1     0   0   +1/2

2s²       1     0    0   -1/2

2p₋₁¹     1     +1  -1   +1/2

2p₀¹      1     +1   0   +1/2

2p₊₁¹     1     +1  +1   +1/2

2p₋₁²     1     +1    -1   -1/2

2p₀²      1     +1   0   -1/2

2p₊₁     (empty orbital)

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
