Question

What are the six known elements for which $\mathit{Z}$is a magic number? Discuss what properties these elements have as a consequence of their special values of $\mathit{Z}$.

Short answer

The six known elements for which $Z$is magic numbers are $2,8,20,28,50$ and $82$. The properties are the element that has a greater number will be the most stable element of the six elements, and the element has very tightly bound nuclei.

Step-by-step solution

Define the atomic number and mass number

An atomic number $Z$is the number of electrons or protons present in the element. The total number of protons and neutrons in an element is the mass number $A$.

Write the properties of the magic number.

The numbers are $2,8,20,28,50$and $82$.

The elements have properties either or both of

1. The element that has a greater number will be the most stable element of the six elements.

2. The element has very tightly bound nuclei.

Hence, six known elements for which $Z$is magic number are $2,8,20,28,50$and $82$. The properties are the element that has a greater number will be the most stable element of the six elements, and the element has very tightly bound nuclei.
