Which elements has least value for electro-negativity Lithium or Krypton?
Lithium has a lower electronegativity than krypton. The electronegativity for lithium is 0.98; the electronegativity for krypton is 3.0. Note that most noble gases in group 18 have no electronegativity at all since the do not make compounds. However, since krypton and xenon do make compounds under some circumstances, they do have a measurable electronegativity.
Can every element in the periodic table be used to make compounds?
No, the elements helium and neon have no known nor likely compounds with any degree of stability at all. Many of the artificial elements cannot in practice be used to make compounds, because they live for too short a time before their radioactive decay to another element. We do know in theory what sorts of compounds they might make, and many of their likely properties.
Do different compounds found together but not combined chemically make up an element?
No, different compounds found together but not chemically combined do not make up an element. An element is defined as a pure substance that consists of only one type of atom, characterized by its atomic number. Compounds are formed from two or more elements that are chemically bonded together. Therefore, a mixture of compounds does not change the fundamental nature of the individual elements present.
Which element is in the same period as helium?
Helium belongs to the 18th group which is known as noble gases/rare gases/zero group elements/inert gases.The other member areNeon(Ne)Argon(Ar)Krypton(Kr)Xenon(Xe)Radon(Rn)There is a vacant space at 118 i.e.marked as Un-Un Octium (Uuo) in the periodic table. If any element occurs that place, then it will be a rare gas.
Does every element in the periodic table of elements have carbon in them?
No. An element, by definition, does not contain any other element. The only element that contains carbon is carbon; however, carbon does make compounds with other elements - for example, carbon dioxide and carbon monoxide with oxygen.
What compounds make up the element cadmium?
No compounds make up elements. Elements make up compounds, so there are no compounds in cadmium since it is an element.
Which elements has least value for electro-negativity Lithium or Krypton?

Note that most noble gases in group 18 have no electronegativity at all since the do not make compounds. However, since krypton and xenon do make compounds under some circumstances, they do have a measurable electronegativity.
What other elements or compounds bond with oxygen to make other elements?
Almost every other element except the elements in group 18 bond with oxygen to form compounds.
Is a copper door knob a compound element or mixture?
A copper door knob is a mixture of copper and other elements or compounds that form the alloy used to make the door knob. Copper itself is an element, but when combined with other elements or compounds to form an alloy, it becomes a mixture.
What are hydrogen's compounds?
well hydrogen itself is not a compound, it is an element. But hydrogen is mixed with many other elements to make compounds such as water h2o. hope this helps
What are the compounds that make up helium?
Helium is an element. It is the second element on the periodic table, therefore containing two protons. It is not made of compounds.
What other element does argon make compounds with?
Fluorine and hydrogen: to form argon fluorohydride.Hydrogen to form argonium or argon hydride.
How are atoms element and compounds related?
Atoms make up compounds and elements.Atoms make up everything in the world.
What compounds make up xenon?
Xenon is an element so it is not made up of any compounds.
Can every element in the periodic table be used to make compounds?
No, the elements helium and neon have no known nor likely compounds with any degree of stability at all. Many of the artificial elements cannot in practice be used to make compounds, because they live for too short a time before their radioactive decay to another element. We do know in theory what sorts of compounds they might make, and many of their likely properties.
Are hydrocarbonbs a compound or an element?
They are compounds because they are make up of more than one element. These are hydrogen and carbon.
What compounds make up life?
CHOSNP or Carbon, Hydrogen, Oxygen, Nitrogen, Sulfur, and Phosphorus are the major element compounds that make up life.
