Transmission Electron Aberration-Corrected Microscope (TEAM) is the only one capable of resolving individual atoms. Scanning Electron Microscopes can resolve a good amount of macromolecules.
The chemical formula for water is H2O. This formula shows the number of atoms in one molecule of water. Therefore, there are two atoms of hydrogen, and one atom of oxygen.
The molecular formula shows the numbers and types of atoms in a molecule but does not show the bonding arrangement between the atoms. It gives the simplest whole-number ratio of the different types of atoms in a compound.
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 chemical formula shows you this. The subscripted number next to each element shows how many atoms are present in a molecule or formula unit. If no number is shown, then only one atom of that element is present.
The molecule that shows 3-heptyne is heptyne. It has a triple bond between the third and fourth carbon atoms in a chain of seven carbon atoms.
One model that shows how atoms are arranged in a molecule is the ball-and-stick model. In this model, atoms are depicted as balls and bonds between them as sticks. This provides a visual representation of the spatial arrangement of atoms within a 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.
It is important to know the relative number of atoms of each element in a compound for the chemical composition.
a zewithalarion shows poth positive and negative; go figure...
A chemical formula provides information about the types and numbers of atoms in a molecule, but it does not reveal the spatial arrangement of those atoms in the molecule. It is a concise way to represent the composition of a substance using chemical symbols and numerical subscripts.
