Having symbols for atoms of different elements allows for a simple and concise way to represent elements in chemical formulas and equations. It helps to distinguish between different elements and enables chemists to communicate effectively about the composition and reactions of chemicals.
Compounds are represented by chemical formulas, which show the types and numbers of atoms present in the compound. These formulas can be written using chemical symbols for individual elements and subscripts to indicate the number of atoms. Examples include H2O for water and CO2 for carbon dioxide.
There are 5 oxygen atoms in O5. Each molecule of O5 contains 5 oxygen atoms.
Examples of metals with their symbols: Iron (Fe) Gold (Au) Copper (Cu) Aluminum (Al) Zinc (Zn) Examples of non-metals with their symbols: 6. Oxygen (O) 7. Nitrogen (N) 8. Carbon (C) 9. Sulfur (S) 10. Fluorine (F)
To find the total number of atoms in 5 molecules of CH4, we first calculate the number of atoms in one molecule of CH4. Each molecule of CH4 contains 1 carbon atom and 4 hydrogen atoms, totaling 5 atoms per molecule. Multiplying this by 5 molecules gives us a total of 25 atoms (5 molecules x 5 atoms per molecule) in 5CH4.
Kitchen examples: wine, beer, vinegar, juice, coffee.
Atomic symbols are used to represent elements, a negative (-) and a psoitive (+) represent electrons and protons, respectively. Chemicals or other compounds are often written as a combination of atomic symbols with subscripts to indicate the presence of multiple atoms.

Subscript
Compounds are represented by chemical formulas, which show the types and numbers of atoms present in the compound. These formulas can be written using chemical symbols for individual elements and subscripts to indicate the number of atoms. Examples include H2O for water and CO2 for carbon dioxide.
Examples of signs and symbols include traffic signs like stop signs and yield signs, religious symbols like the cross or the Star of David, and mathematical symbols like the plus sign or the equal sign.
