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

Answer:
physical cosmology, the Big Rip is a hypothetical cosmological model concerning the ultimate fate of the universe, in which the matter of the universe, from stars and galaxies to atoms and subatomic particles, and even spacetime itself, is progressively torn apart by the expansion of the universe at a certain time
