Answer:
The possible values of l are 2 and 3
Explanation:
Each electrons have four quantum numbers:
- n: the principal quantum number, which value matches with the energy level of the electron.
- l: the secondary quantum number, which value can be from 0 to n-1
- m: the magnetic number, which value can be from -l to l
- sp: the spin number which value can be -1/2 or +1/2
In this case, n=4 so the values of l are:
l=0, 1, 2, 3
Now, if:
- l=0 the value of m is m=0
- l=1 the values of m are m= -1, 0, 1
- l=2 the values of m are m= -2, -1, 0, 1, 2
- l=3 the values of m are m= -3, -2, -1, 0, 1, 2, 3
Being all that said, l can be either equal to 2 or 3
Water is always on the move. Rain falling today may have been water in a distant ocean days before. And the water you see in a river or stream may have been snow on a high mountaintop. Water is in the atmosphere, on the land, in the ocean, and underground. It moves from place to place through the water cycle.
Where's the water?
There are about 1.4 billion km3 of water (336 million mi3 of water) on Earth. That includes liquid water in the ocean, lakes, and rivers. It includes frozen water in snow, ice, and glaciers, and water that’s underground in soils and rocks. It includes the water that’s in the atmosphere as clouds and vapor.
If you could put all that water together – like a gigantic water drop – it would be 1,500 kilometers (930 miles) across.
Answer:
The Great Lakes were formed by a retreating glacier that dug out large basins. Then as the glacier melted, the water filled in those basins
