The total number of electrons that can be accommodated in all the orbitals having principal quantum number 2 and azimuthal quantum number 1 are
A. 2
B. 4
C. 6
D. 8
Correct Answer - C
(c) When n=2 and l=1, then subshell is 2p. The number of orbitals in p-subshell
`=(2l+1)=(2xx1+1)`
`3`
Total (maximum) number of electrons
`2xx`numberof orbitals
`=2xx3`
= 6
(as each orbital contains 2 electrons)
Correct Answer - B
S=1
t=0
`u=-1/2,1/2`
No of subshell=1 , No of orbital=2
No of electrons =8
S=2
t=0,3
`u=-1/2,1/2`(for t=0)
u=-2,-1,0,+1,+2(for t=3)
No of subshell=2, No of orbital=7

Correct Answer - 24
In `M^(4+)` ion total number of electrons =20
Electronic configuration `=(1s^2)/2 (2s^2 2p^6)/8 (3s^2 3p^6 3d^2)/10`
Number of electrons in metal = number of protons =4+20=24
Correct Answer - 36
First gas which contains d-electrons is Kr.
`1s^2 2s^2 2p^6 3s^2 3p^6 3d^10 4s^2 4p^6`
Total number of d-electrons = 10
Total number of p-electrons =6+6+6=18

Azimuthal quantum number (l) :
Azimuthal quantum number is also known as subsidiary quantum number and is represented by letter l.
It represents the subshell to which the electron belongs. It also...
Correct Answer - B
We have `f(x) = sin^(-1)x`, having range `[(pi)/(2), (3pi)/(2)]`
Consider the function `h(x) = (pi - sin^(-1) x)`, where
`sin^(-1) x in [-(pi)/(2), (pi)/(2)]`
Clearly, function `f(x)...
