Question

Classify the following nuclei into stable or unstable. Justify your answer for each one.

Answer 1

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
