【What kinds of atoms are there?】

《Chemical elements of super uranium》

Plenty of the chemical elements like the super uranium are so unstable that they will be broken at once when it's created.😱

It's just their experimental data remain.It resembles a situation as if a person didn't exist,but its family registration was left.😃

【What is the periodic table of the elements 元素周期表？】

The periodic table of the elements is the chemical elements are lined up with an order of atomic numbers,and return at an appropriate places.😃

Its concept is exactly the same as calendars.Its dates stand in lines with orders of its numbers,and return every 7date.😚

《Group》

It is the group which is important in the periodic table.There are numbers from 1 to 18 above the periodic table.😃

We call the groups of the atoms under each number 1group,2group and so on.The group is equivalent to a date on the calendar.🙋
