H2CO (I assume that the "2" is meant as a subscript of the "H") is a molecule called formaldehyde. It is called a molecule since it consists of more than one atombonded together (it consists of two hydrogen, one carbon, and one oxygen atom). Elements are made up of atoms; compounds are made up of molecules.
Its an element and an atom.
There is one atom of that element in the molecule.
Polar
An element is an atom or molecule made of a single type of atom. A compound is a molecule made of two or more different elements.
Chemical formulas represent the number and element of each type of atom in a molecule.
Its an element and an atom.
an atom
An atom for an ELEMENT and a molecule for a COMPOUND.
The atom of an element is smaller than a molecule.
"element" (2 make up a molecule)
H2CO is a polar molecule. It contains a carbonyl group, which is a C=O bond. O is an extremely electronegative atom, compared to carbon.
An element, atom, crystal, compound, and molecule are all forms of matter.
One carbon atom is an element. You must have two or more atoms to make a molecule.
CHNaO3 + C2H4O2 -> NaC2H3O2 + H2CO Following this the Carbonic Acid ( H2CO ) dissociates in the following reaction: H2CO -> H2O + CO2
There is one atom of that element in the molecule.
