because they are smart
Scientists often determine the shape of a molecule using techniques like X-ray crystallography, nuclear magnetic resonance (NMR) spectroscopy, or computational modeling. These methods help visualize the arrangement of atoms in a molecule, allowing scientists to understand its three-dimensional structure and shape.
Mass
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.
The subscript 2 in a chemical equation typically indicates that there are two atoms of that element present in the compound or molecule. It represents the stoichiometry of that element within the compound.
Other scientists
The structural formula show the spatial aspect of the molecule.
Scientists show creativity by expirimenting in different ways.
A combination of symbols and numbers that describes a molecule is called a chemical formula. It represents the types of atoms present in the molecule and their respective ratios. The symbols represent the chemical elements (e.g., H for hydrogen, O for oxygen) and the numbers indicate the number of atoms of each element in the molecule. Chemical formulas are essential for understanding the composition and structure of molecules in chemistry.
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.
If you are talking about covalent bonded molecules, then you would call them polar molecules. This means one element is hogging the shared electrons more than the other. This would make one element partially charged positively, and the other element partially charged negatively The signs to show partially charged looks like an incomplete 8.
