Answer:
The values for spin quantum number +1/2 and - 1/2
Explanation:
Principal quantum number denoted by (n) is used to describe the shell or orbits that electrons are found. Principal quantum number can assume a value of n= 1,2, 3, 4,5............ which indicates K, L, M, N, O shell respectively.
To know the maximum number of electrons in each shell, the formula (2n²) can be used. The letter 'n' denotes the values of principal quantum number 1,2,3,4
For example
- n=1 (K shell) has maximum number of 2 electrons
- n=2 (L shell) has the maximum number of 8 electrons
- n=3 (M shell) has the maximum number of 18 electrons
- n=4 (N shell) has the maximum number of 32 electrons
All the electron in each shell will have a spin quantum number of +1/2 and - 1/2. One electron in each degenerate orbital will spin up (+1/2) while the other electron will spin down (-1/2).
Answer:
0.259 nm is the distance between the red and green balls.
Explanation:
Let the distance between the red and green ball be = RG =x
Let distance between blue and red ball = RB =y = 0.448 nm
Let distance between blue and green ball = GB = z
In triangle RGB
( Pythagoras theorem)
..[1]
In triangle GOB
( Pythagoras theorem)
GO = OB = sides of cube
..[2]
Using [2] in [1]:
0.259 nm is the distance between the red and green balls.
Answer:
Very Likely B.
Explanation:
Increasing temperature inside a closed container - keeping everything constant will make pressure increase. Because the energy being held by the molecular (the gas molecules) rises, the container may expand meaning the volume increases.
Answer : Option A) Deforestation.
Explanation : Factors related to deforestation can lead to desertification in presence of natural drought.
As natural drought hit area is an area which has low amount of water supply in the land. It is also called as below average precipitation land when drought area is deforested it will lead to desertification. As the plants in the drought area are the reason why their is at least low water is found, if these vegetation is deforested then it will lose its capacity to hold water and the land will be deserted.
