The number of subshells within a certain shell can be identified using the orbital angular momentum quantum number "l"
"l" is given values from zero till (n-1)
So, for n=6
l is given the following values: 0,1,2,3,4,5
Counting the number of subshells, we will find that the shell with n=6 has 6 subshells
Answer:
Energy is not created but transformed meaning the energy just transformed into a different type meaning at all points of the ramp the energy stays the same because all of its energy is just transformed into kinetic energy.
