Magic number is any number in electron shells that suggest stability. It corresponds to total number of electrons in filled electron shells.

If an electron is having magic number, then it forms stable bonds.

Explanation:

The magic numbers are 2,10,18,36,54, 86 and 126. This refers to the total number of electrons that an electron can have when it is completely filled.

Atomic nuclei which carries either of these nucleons have high binding energy as compared to others. Hence, they have high stability. Bonds in such elements are more strong.

Radioactive decay of such elements is very slow.

Eugene Winger coined the term "magic number".

Why is climate change a concern when it comes to animal behavior and ability to reproduce
kow [346]

Answer:

hope this helps! :)

This means that changing global temperatures could alter the ratio of sexes produced, making it harder for these animals to find mates
