Answer:
n = 756.25 giga electrons
Explanation:
It is given that,
If the charge on the negative plate of the capacitor,
Let n is the number of excess electrons are on that plate. Using the quantization of charges, the total charge on the negative plate is given by :
e is the charge on electron
or
n = 756.25 giga electrons
So, there are 756.25 giga electrons are on the plate. Hence, this is the required solution.
We have that all except Uranium is Stable
From the question we are told
Classify the following nuclei into stable or unstable.
- Generally a nuclei is made up of Neutrons and Protons
- A stable nuclei is one with its Protons and Neutrons equal or Very close
Generally the equation for Stable Nuclei is mathematically given as
n=p
Therefore
For U
P=92
N=238-92
N=146
Therefore Unstable
For N
P=7
N=9
Therefore Stable
For Be
P=4
N=6
Therefore Stable
For Ne
P=10
N=10
Therefore Stable
For Al
P=13
N=14
Therefore Stable
For Ar
P=18
N=21
Therefore Stable
For Ni
P=28
N=36
Therefore Stable
For O
P=8
N=7
Therefore Stable
For He
P=2
N=2
Therefore Stable
For Sc
P=21
N=20
Therefore Stable
For Li
P=3
N=3
Therefore Stable
