Type the max number of electrons that can be present in each shell or sub below n = 5 shell __
n = 2 shell __
n = 2 l = 0 sub: __
n = 2 / 1 sub: __
3d sub: __
2s sub: __
5f sub: __

Explanation:

The maximum no. of electrons in a shell is given by. 2n^2 .

So for

n= 5 , 2× 5× 5 = 50

n=2 , 2×2×2 = 8

For a sub shell the maximum no. of electrons possible is given by 2(2l + 1)

So for n= l= 0

2 [(2×0) +1] = 2

for n=2 l=1

2 [(2×1) + 1] = 6

3d

d sub shell has l= 2 quantum number

Therefore 2[ (2×2) + 1] = 10

2s

s sub shell has l=0 quantum number

2 [(2×0) +1] = 2

5f

f sub energy level has l=3 quantum number

So 2[ (2×3) +1 ] = 14

The azimuthal quantum numbers for the sub shells are as follows

( s ---> 0

p> 1

d> 2

f > 3 )

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
