The amount of electrons, neutrons, and protons it has in it, Also the spot of the element on the periotic table (medal, gass etc.)
All hydrogen atoms are the same but they are different from the atoms of other elements.
one, and binary compounds don't always contain hydrogen, just 2 different elements
No. Hydrogen an oxygen are both elements. Elements do not contain other elements.
Hydrogen and oxygen are already 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.
No. Both chlorine and hydrogen are elements. Elements cannot contain other elements.
Chemical formula for water is H2O. Water is made of elements Hydrogen and Oxygen.
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.
Its made from different elements
yes. water is H2O which is hydrogen mixed with oxegen, and that's just one of a lot of different chemical formulas involving hydrogen.
Hydrogen is different than all the other elements
