Hydrogen is unique among the elements, something of an oddball. It does not fit well into the other groups such as the metalloids, halogens, or alkali metals, so it is given its own group.
No. Hydrogen and helium are separate elements. Elements do not contain other elements. But an element can give off or take electron from other elements.
No. Both chlorine and hydrogen are elements. Elements cannot contain other elements.
No. Hydrogen an oxygen are both elements. Elements do not contain other elements.
Hydrogen can react with practically all other elements.
None. Hydrogen, oxygen, and carbon are all elements. Elements do not contain other elements.
Hydrogen is separate from the rest of Group 1A elements because it displays unique properties that do not fit the typical characteristics of alkali metals (Group 1A elements). For example, hydrogen can form both positive and negative ions, while other Group 1A elements typically form only positive ions. Additionally, hydrogen can exhibit nonmetallic properties in addition to metal-like behavior, setting it apart from the rest of Group 1A.
Hydrogen, like other elements are vegan.
Hydrogen and oxygen are already elements. Elements do not contain other elements.
No, hydrogen and oxygen are two separate elements. Hydrogen is a chemical element that exists as H2 molecules, while oxygen exists as O2 molecules. Water (H2O) is formed when hydrogen combines with oxygen.
None: Hydrogen and chlorine are both chemical elements and therefore do not contain any other chemical substances.
When gaseous hydrogen and gaseous chlorine are mixed each other, they react vigorously to form hydrogen chloride (HCl). The only way to separate elements from the gas HCl is electrolysis where chlorine is discharged at cathode and the other at anode.
