<span><span>stratovolcano (or composite volcano) — a conical volcano consisting of layers of solid lava flows mixed with layers of other rock.

cinder cone volcano — doesn’t have any horizontal layers, and is instead a steep conical hill of tephra (volcanic debris) that accumulates around and downwind from the vent.

shield volcano — a type of volcano built entirely or mostly from fluid lava vents. They are named like this because when viewed from above, you can see just how massive and imposing they are – like a warrior’s shield.</span></span>
The H-atom has fourth energy level with n=4.
This
energy level can have values of orbital angular momentum l = 0, 1, 2, 3
Now each l can also have magnetic momentum ml from – l to l.
Therefore,
l = 0
<span>ml = 0 </span>
l = 1
ml = -1, 0, 1
l = 2
ml = -2, -1, 0, 1, 2
l = 3
ml = -3, -2, -1, 0, 1, 2, 3
Now adding up all the number of ml’s will give us the total
number of orbitals:
orbitals = 1 + 3 + 5 + 7
orbitals = 16
Alternatively, we can simply use the formula:
<span>orbitals = n^2 = 4^2 = 16</span>
