【What is an isotope? 同位体】

《Hydrogens' isotope》

Those three hydrogens have same chemical reactionrs altogether,so we can't separate them when making use of their chemical nature.😃

However,H1 weighs half of H2,so their physical nature such as speed of their motions and strength of their oscillations 振動 are also different,so we can separate them when taking advantage of nature of their motions.😃

By the way,to my sorrow,I'm good at neither chemistry nor physics,so I can't understand why we can't separate them with the former way,but we can do with the latter one.I should have studied harder when being in high school.😳

【Is an atomic nucleus stable?】

While its atomic numbers are same,its amount of mass are different.When giving an example,there are all sorts of hydrogens which have three different isotopes.😃

The difference between them is a number of neutrons in the atomic nucleus.Then what kind of influence do the isotopes have in radioactivity of the atoms? 😚
