Answer 1

27. Why can a p sublevel hold six electrons while the s sublevel can hold no more than two electrons?
Ans: Because there are three p-orbitals, and only one s-orbital.

28. What do electrons and light have in common?
Ans: Both are quantized.

29. Of a set of four quantum numbers, how many of these numbers can be shared by more than one electron of the same atom?
Ans: There are three of them: n, l, and m.

30. When does an electron in an atom have the lowest related?
Ans: Do not understand your question. Please check.

31. How are the frequency and wavelength of light related?
Ans: ν = c/λ
where ν is the frequency in 1/s, c the speed of light 2.998x10^8m/s, and λ the wavelength in m (1nm = 10^-9m).

32. Why does an electron occupy the 4s orbital before the 3d orbital?
Ans: Because the energy of the 4s orbital is slightly lower than the energy of the 3d orbital.

33. The element sulfur has an electron configuration of 1s2 2s2 2p6 3s2 3p4
Ans: What is your question?
