Question

For a particular element, a photon of yellow light of wavelength of 585 nm resulted when an electron fell from the third energy level to the second energy-level. From this information we can determine The energy of the n = 2 level. The energy of the n = 3 level. the sum of the energies of n = 2 and n = 3. the sum of the energies of n = 1, n = 2, and n = 3.  The difference in energies between n = 2 and n = 3. Which of the following electronic transitions in a hydrogen atom would have the highest energy? N = 4 to n = l n = 4 to n = 2 n = 2 to n = 1  n = 4 to n = 3 n = 1 to n = 0 What type of orbital is designated n = 2, t = 1, m_t = -1? 2p 3p 2s 3s 4p What is the maximum number of orbitals possible when t = 1? Zero one three five nine When t = 3, what set of orbitals is designated? G p f d s What name is given to a region of an electron probability density graph where probability of finding the electron is zero? Node wave function orbital lobe excited state

Explanation / Answer

86)E = 109677 ((1/n1^2) - (1/n2)^2)
here E = energy change when an electron jumped from higher energy level to lower energy level.
Answer : e
87)E = 109677((1/1) - (1/4))
E = 82257.75 J
so E is inversely proportional to square root of orbit number, so n value increases then E value decreases.
Answer : C
88) n = 2 means orbit number is 2
l = 1 means sub shell is p
ml = -1 means orientation of orbital.
Answer : a (2p)
89) l = 1 means it is p subshell and it has three orbitals
Answer : C
90) l = 0 means S, l = 1 means p , l = 2 means d means l = 3 means f
Answer : c
91) Answer : A it is called Node.
