Lewis dot structures show how an atom's electrons work together in a certain molecule. They also show what a certain molecule will look like.
The molecular formula doesn't show the arrangement of atoms within the molecule or the way atoms are bonded to each other. It also doesn't provide information about the three-dimensional structure of the molecule. Additionally, the molecular formula does not reveal any information about the physical and chemical properties of the molecule.
Ball-and-Stick Model
Models of carbon backbones show the arrangement of carbon atoms in a molecule. They provide information about how carbon atoms are connected to each other, which can determine the shape and properties of the molecule. Carbon backbones help illustrate the structural framework of organic molecules.
The structural formula show the position of atoms in a molecule.
Mass
the elements which are very essentiel for the growth of plants are called macro nutrients.these nutrients are required in fairly large quantity show they aare called macronutrients.
The structural formula show the spatial aspect of the molecule.
You can record a macro and before starting the recording you can use i key as assigned key to run the macro. Also, if you have an existing macro to which you want to assign i key then Press Alt + F8 which will show you the list of existing macro. Click on Edit and type the i in the assign key box. Remember Ctrl is my default. So, if you want the macro to have Ctrl SHIFT I then turn on the caplock. Your question is not very decriptive in nature.

A molecule is the smallest unit of most chemical compounds. Scientists use a kind of shorthand called a chemical formula that shows the type and number of elements in a molecule. For example, a water molecule is written as H2O, which means there are 2 atoms of Hydrogen and 1 atom of Oxygen.

Lewis structures are diagrams that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule. They are also called Lewis dot diagrams, electron dot diagrams, and electron dot structures. See the link below for Lewis structure.
