expanded structural formala
A chemical formula that shows the arrangement of atoms and their bonds. As the previous guy said, it is a representation that shows the arrangement of atoms and their bonds. Types are: 1. Lewis structures...simple representation which do not show the arrangement of atoms in the 3-d space. Hence generally used for small molecules. for the 3-d arrangement, we have Fisher, Newman, and Haworth projections.
The molecular formula for dry ice is CO2. Its structure is approximated by a 120o angle, with 2 double bonds connecting each oxygen molecule to the carbon molecule. The molecular formula for dry ice is CO2. Its structure is approximated by a 120o angle, with 2 double bonds connecting each oxygen molecule to the carbon molecule.
If you're asking "do two or more atoms in a chemical bond make a molecule?", Wikipedia defines a molecule thus:A molecule is defined as a sufficiently stable, electrically neutral group of at least two atoms in a definite arrangement held together by very strong (covalent) chemical bonds.... so your answer is:yes.
Any number of atoms joined together by means of chemical bonds is called a molecule. The number of atoms in a particular molecule varies.
The name of the energy that holds atoms together in a molecule is called chemical bonds.
A molecular formula shows the types and numbers of atoms in a molecule, but not the bonds. A structural formula shows the way in which the atoms bond.
The bond in carbon tetrachloride are polar covalent, but the CCl4 molecule a a whole is nonpolar due to the symmetrical arrangement oft he bonds.
The empiracle formula shows the ratio of the individual elements in a compound, and the molecular formula shows the actual number of each elemental atom in each molecule (which will be equal to the empiracle formula or a whole number multiple of it). However, it is the structural formula that shows how the individual atoms are connected.

O-O=O, with an angle between the single and double bonds making the molecule slightly polar. Periodically, the single and double bonds swap.
The proper formula of ammonia is NH3. A molecule of ammonia contains three covalent bonds, one from each of the hydrogen atoms to the only nitrogen atom in the molecule.
That is a structural formula. For example, the chemical formula for water is H2O and its structural formula is H-O-H, which shows how the atoms are arranged in the molecule.

Salt (NaCl) is formed by ionic bonds, so it does not come in molecules. Instead, it is called a formula unit, and there are two atoms in this particular one.
