Hydrogen is known as a element and a compound. Hydrogen is a light element with one proton and a gas compound with two hydrogen atoms.
hydrogen gas is H2 so it only contains hydrogen. therefore it is an element
Hydrogen is an element, number 1 on the table of elements actually.
Hydrogen is the most common element in the universe, and in the Sun.
Hydrogen is a non metal element. Atomic number of it is 1.
Hydrogen is the smallest element. It has only 1 energy level. It is a gas element.
pure water is a compund because it's contain hydrogen & oxygen .
Compound
Iron is a chemical element.
It is a compound, because an element, such as hydrogen, and another, such as oxygen are in Ethyl Alcohol.
No. A compund is a mixture of different atoms. E.g. H2O (water) is a compund of both Hydrogen (x2) and Oxygen. If the substance was one pure type of atom then even then no, because even then some of them would be isotopes of that element.
For example sodium hypochlorite (NaClO) is a bleach compund.
Element's have only one atom, while compund's have more that one atom.
A chemical symbol represents an element. A chemical formula represents a compund. a chemical formula is like this H2O, that is water, a chemical symbol is just this H, that is hydrogen.
it's an element!
Hydrogen is an element. So the only element in hydrogen is hydrogen.
The element Hydrogen .
Hydrogen (H) is an element. Hydrogen gas (H2) is a molecule.
