Hydrogen
methane is a compound as one carbon atoms combines with 4 hydrogen atoms.
Boron is lighter than carbon and uranium.
Hydrogen, uranium, and wire.
Ethanol (ethyl alcohol) is a compound comprised of three different elements, carbon, hydrogen and oxygen. Any substance that chemically combines two or more elements is referred to as a compound.
Carbon is not an element of water. Water is composed of hydrogen and oxygen. Carbon is a separate element.
Carbon dioxide contains carbon and oxygen. Water contains hydrogen and water. Therefore, to combine with oxygen to form CO2 and H2O, butane must contain carbon and hydrogen.
Isotopes are atoms of the same element with the same number of protons but different number of neutrons. Some examples of atoms with isotopes are hydrogen (protium, deuterium, tritium), carbon (carbon-12, carbon-13, carbon-14), and uranium (uranium-235, uranium-238).
This chemical element is carbon.
No hydrogen is the lightest element.
During combustion, hydrogen and carbon react with oxygen to form water and carbon dioxide. The hydrogen combines with oxygen to form water vapor (H2O), while carbon combines with oxygen to form carbon dioxide (CO2).
Oxidation process causes rusting in Iron. Oxidation is the same process when Oxygen combines with Hydrogen to form Water and Carbon dioxide.
All of them. There are no elements lighter than hydrogen. It has only two atomic particles, and you cannot have an element with less.
