Which of the following excited state electron configurations of C would require the longest wavelength of light to produce? Question 23 options:

1s22s22p13s1

1s22s22p2

1s22s22p24s1

1s22s22p13p1

Explanation:

Well ik its not math for this but for the first one if u add

22+22+13+1 u get 58

then second one 1+22+22+2=47

1+22+22+24+1=70

1+22+22+13+1=59

U notice how that most or some are all going up to 50 except the third one

So that means its 1s22s22p24s1

water is used to store them because it would keep the radiation from getting out in the open and causing harm to the workers

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
