Alkali metals and halogens.
no
Oxygen combines easily with many other elements and compounds
Atoms of elements in group 18 (noble gases) do not easily combine with other elements to form compounds.
The elements in group 1 combine easily with other elements to form compounds because they are trying to get rid of their extra electrons. That is why, for example, potassium will react strongly in water. Hope this helps.
There Are No Other Elements or Compounds And Mixtures
Uranium has an extensive chemistry- its quite reactive and forms many very interesting compounds.
Helium is a member of the noble gas family of elements. The elements of this family do NOT usually form compounds with other elements.
No, the other way around. Kind of. Elements are made of compounds of atoms.
Inorganic compounds - usually made from elements other than
Almost every other element except the elements in group 18 bond with oxygen to form compounds.
ReactivityThe ease and speed with which an element combines with other elements and compounds is called the "reactivity" of the element.
Usually mixtures are easiest to separate into their substances.
