A: (2)>(1)>(4)>(3)
B: (1)>(2)>(4)>(3)
C: (1)>(2)>(3)>(4)
D: (3)>(4)>(1)>(2)
A: (2)>(1)>(4)>(3)
B: (1)>(2)>(4)>(3)
C: (1)>(2)>(3)>(4)
D: (3)>(4)>(1)>(2)
举一反三
- 写出下列各种情况的合理量子数。 (1)n = ,l = 2, m = 0, ms = +1/2 (2)n = 3,l = ,m = 1,ms = -1/2 (3)n = 4,l = 3,m = 0,ms = (4)n = 2,l = 0,m = ,ms = +1/2 (5)n = 1,l = ,m = 0 ,ms =
- 对下列各组轨道填充合适的量子数,并指出电子所处的原子轨道。 (1) n = ? , l = 2, m = 1, ms = +1/2 (2) n = 3 , l = ? , m = 1, ms = -1/2 (3) n = 4 , l = 0, m =?,, ms = +1/2 (4) n = 2 , l = 0, m = 0, ms = ?
- 下列各组量子数中错误的是 ( )? n=3,l=2, m=0, ms=+1/2|n=2, l=2, m=-1, ms=-1/2|n=3, l=1, m=-1, ms=-1/2|n=4, l=1, m=0, ms=-1/2
- 下列四个量子数组合正确的是 A: n = 3, l = -3, m = 0, ms = 0 B: n = 4, l = 3, m = -1, ms = +1/2 C: n = 2, l = 2, m = -1, ms = -1/2 D: n = 3, l = 2, m = 3, ms = +1/2
- 下列各组量子数中合理的是 A: n=3,l=3,m=-3,ms=+1/2 B: n=3,l=2,m=-2,ms=–1/2 C: n= 4,l=-1,m=0,ms=+1/2 D: n= 4,l=1,m=-2,ms=–1/2
