Question

i need the answers to all 10 questions please

principal quantum number, angular momentum quantum number, magnetic (1) The shape of an electron orbit is determined by: quantum number, or electron spin quantum number. (2) For the sad shell, the number of possible orbits is: n =5 50 n=1 n2 n: 3 z 9 19 Questions 2. 6, 8, 9, 12, 18 (3) For the so shell, the maximum number of electrons is: 2, 6, 8, 9, 12, 118 [4] For the subshell ? - 3, the number of possible orbits is: 3, 5, 7, 9, 15, 21 (5) The number of subshells in the 5" shell is: 4, 5, 8, 10, 20 [6] When there are 3 or more electrons, the number of electrons in the outer most orbit cannot exceed: 2, 4, 6, 8, 10 [7] An electron enters into an orbit with spin up. If another electron enters into that same orbit, it must have: spin polar, spin up, spin down, spin right, spin spherical. [8] An electron always falls to the orbit that is closest to the nucleus as possible. This statement is: correct or incorrect. [9] A valence electron can freely move from atom to atom when there are: 1-2 valence electrons, 3-4 valence electrons, 5-6 valence electrons, 7-8 valence electrons. [10] If close enough, a positively charged proton can exert an attractive force on another positively charged proton. This statement is: correct or incorrect 19

Answer 1

1) Angular momentum Quantum number

2)For n=3, l has three values l= 0,1,2

For l = 0 ,no of orbit = 1

For l = 1 ,no of orbit = 3

For l = 2,no of orbit = 5

So total number of orbits = 9

3) According to Bohr Bury Scheme ,Number of electrons for a given n = 2n^2

For n = 3, it is 18

4)No of orbits for a given l is 2l+1

For l=3, 2l+1=7

5)Number of subshells for n=5 is 5

6) Number of valence electrons cannot exceed 4

7)spin down

8)Incorrect

9)If there are 1-2 valence electrons they can move freely.

10)The statement is correct if the separation is very small such that strong force interaction occurs between the two protons.
