What is the name the elements combined in compound AI2O3?
Aluminum and oxygen. The first two letters in the compound are Al, not AI, so the compound aluminum chloride is written Al2O3. Al is the symbol for aluminum and O is the symbol for oxygen.

Elements are give symbols consisting of letters, and these are related to the names of the elements (in some language at some date). There are 26 letters in many alphabets, but more than four times that number of elements. So it is necessary to use some mechanism to distinguish among elements with names that start with the same letter. Adding numbers is done to designate the number of atoms in a compound, the isotope, and so on. The best solutions is to use pairs of letters for most elements.

Why do you use chemical symbols when writing the names of compounds?
The letters are the symbols of elements and ions that are contained in the compound. For example H2O tells us that the molecule (water) contains two atoms of hydrogen and one of oxygen. The compound water can be broken down into its separate elements in several ways.
Is vegetable soup a compound or mixture?
Vegetable soup is a mixture, because a compound is a combination of 2 or more elements, like water, (H2O), or glucose, (C6H12O6). Soup is a mixture of different compounds, like salt, (NaCl), water, (H2O), and vegetables, which have a lot of everything. Those numbers are supposed to be smaller and near the bottom of the letters, but I don't know how to do that by typing.
