False; practically all the chemical elements have many uses.
All of the elements in the periodic table
All compounds are made of two or more elements.
This question is a little ambiguous. If you mean 'how many elements have mass,' the answer is 'all elements have mass.' There are 117 known elements, and scientists theorize that there may be as many as 130 or more.
118 (all elements from #1 to #118).
All the elements after Uranium (U).
"H" or Hydrogen is an element, there are no other elements in it because all elements are pure substances.
there are 5 atoms (1Na 1Cl and 3O) and they are all elements.
All of the elements in group 8A have this electron configuration except for He! (So a total of 5 elements)
All the elements listed on periodic table has symbols for them.There are total 118 elements in periodic table.
All elements can and many often do form positive ions.
There are many elements that have only one naturally occurring isotope. When you get to transuranic elements the elements all have no naturally occurring isotopes. But all elements have isotopes, they just have to be created, maybe in a nuclear reactor or particle accelerator or a supernova explosion.
