Ammonia (NH3) has 3 hydrogen atoms. N is nitrogen.
Hydrogen bromide is a compound, not an element. It is made up of hydrogen and bromine atoms chemically bonded together.
methane is a compound as one carbon atoms combines with 4 hydrogen atoms.
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.
Oxygen on its own is an element because it consists of only one type of atom. In water, oxygen combines with hydrogen atoms to form a compound. Compounds are substances made up of two or more different types of atoms chemically bonded together.
Oxygen combines with Hydrogen to form water. The chemical formula for water is H2O, which indicates that two hydrogen atoms bond with one oxygen atom.
Sucrose can be decomposed chemically as it is a compound composed of carbon, hydrogen, and oxygen atoms. Sodium is an element, and ethanol is a compound made of carbon, hydrogen, and oxygen atoms, but water is a compound that cannot be decomposed chemically as it is already in its simplest form.
Hydrogen(H)& Oxygen(O) are the two chemical elements that make up a water molecule. The Chemical formula for water is 'H2O' This tells us that there are two atoms of the element hydrogen and one atom of the element oxygen in a water molecule. Their bonding arrangement is 'H-O-H' .
In general, when a chemical bond forms between two or more atoms, it creates a molecule.
All atoms in the beginning were hydrogen atoms.
In an element.
hydrogen atoms
Molecular hydrogen has two atoms, both which are of the same element - hydrogen.
