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.
H2CO (formaldehyde) is a polar covalent molecule. The oxygen atom is more electronegative than carbon and hydrogen, resulting in an uneven distribution of electrons and a net dipole moment in the molecule.
There is one atom of that element in the molecule.
The bond angle of formaldehyde (H2CO) is approximately 120 degrees. This angle is due to the molecule's trigonal planar geometry, which results from the repulsion between the electron pairs in the molecule.
An atom is the smallest unit of matter that retains the properties of an element. A molecule is a group of atoms bonded together. An element is a substance made up of only one type of atom.
Phosphorus is an element that exists as individual atoms. It is not a molecule.

an atom
The atom of an element is smaller than a molecule.
CHNaO3 + C2H4O2 -> NaC2H3O2 + H2CO Following this the Carbonic Acid ( H2CO ) dissociates in the following reaction: H2CO -> H2O + CO2
"element" (2 make up a molecule)
One carbon atom is an element. You must have two or more atoms to make a molecule.
An element, atom, crystal, compound, and molecule are all forms of matter.
An atom for an ELEMENT and a molecule for a COMPOUND.
There is one atom of that element in the molecule.
The bond angle of formaldehyde (H2CO) is approximately 120 degrees. This angle is due to the molecule's trigonal planar geometry, which results from the repulsion between the electron pairs in the molecule.
H2CO (formaldehyde) is a polar molecule because it has a slight imbalance in electron distribution due to the electronegativity difference between the carbon and oxygen atoms. This results in a net dipole moment, making it polar.
A molecule of an element is a molecule made up of the same substance that can exist as an atom; for example, oxygen as O2.
