Look at how far away the element is from thenoblegasses
Because people are always finding more elements!
I know that there are over a hundred but you can't always say because when more elements are discovered they are put on the periodic table on the standard table there are 118,
Cobalt has always been an element.
No, because as the days and years go past, more scientists will find out more information on the periodic table. When they find out information on the periodic table, sometimes new elements are found, adding new elements on the periodic table causes it to change.
The difference in atomic number between adjacent elements is always one (1).

Almost all the lower elements in the periodic table will always be radioactive.
There are two elements that are liquid always. They are bromine and mercury

Transition elements reside in the Transition Metals section of the Periodic Table. Groups in this section always contain four elements. This section has most of the known elements in and it includes the Lanthanides and Actinides.
I am not sure entirely what you mean but there are lots of elements that go around in pairs, e.g hydrogen, oxygen, nitrogen amongst others.
In a way, however, about 3-4 elements are added each year, most of the NEW ones are ''non-earth elements.''
you can always search periodic table on google.
u know how Li has one valence electron and then on the other side were neon and stuff is and how it has a full outer orbital because as u read 4rm left to right the group/family will always have the same valence electron
