Question

50 Questions n:3 18 [1] The shape of an electron orbit is determined by: principal quantum number, angular momentum quantum number, magnetic quantum number, or electron spin quantum number. [2] For the 3rd shell, the number of possible orbits is: 2, 6, 8, 9, 12, 18 (3) For the 3"shell, the maximum number of electrons is: 2, 6, 8, 9, 12, 18 [4] For the subshell ? - 3, the number of possible orbits is: 3, 5, 7, 9, 13, 21 [5] The number of subshells in the 5th 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. 19 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. tho Lf close enough, a positively charged proton can exert an attractive force on another positively charged proton. This statement is: correct or incorrect.

Answer 1

1. The shape of electronic orbit is determined by angular momentum quantum number (l).

l= 0, spherical

l=1 ,polar

l=2, coverleaf
