Ok, an atom is supposedly the smallest indivisible unit( at least in basic chemistry)
Now an atom is composed of 3 baser particles, Protons, Neutrons and electrons.
The Proton's are significant, since this is the particle that gives the atomic number to an element in the Periodic Table. It is also how a chemist defines an element. So for example 1 proton, is the atomic number 1, is the first element on the periodic table, and it is Hydrogen. Hydrogen uses the chemical symbol H
Second example 8 protons, is the atomic number 8, and is the 8th element on the periodic table, Oxygen is it's name. Oxygen uses the chemical symbol O.
Now for the formulae, H2O, is the chemical formula for Water, and the H stands for Hydrogen. The "2" symbolizes that you have 2 components (or atoms) of Hydrogen and the O stands for Oxygen. There is only one atom of Oxygen so it is just understood that with no number attached to the formula, that there is only the one atom.
So the formula H2O shows the elements that are combined to represent the water molecule. This allows a chemist who is trained to read the formula to easily understand the composition of the elements that make up the molecule.

How are atoms of different elements similar and how are they different?
Atoms of different elements are similar in that they all contain protons, neutrons, and electrons. However, they are different in terms of their atomic number (number of protons), atomic mass (sum of protons and neutrons), and electron configuration, which determines their chemical properties.
What is a substance in scientific terms?
In scientific terms, a substance is a type of matter that has constant chemical composition and distinct properties. Substances can be either elements (made up of one type of atom) or compounds (made up of different types of atoms bonded together).
What did john dolton do for atoms?
John Dalton developed the atomic theory, which proposed that all matter is composed of tiny, indivisible particles called atoms. He also introduced the concept of atomic mass and explained chemical reactions in terms of atoms combining and rearranging. His work laid the foundation for modern chemistry.
What characteristics do metalloid elements share with metal and non metal elements?
Metalloid elements share characteristics with both metals and nonmetals. Like metals, metalloids can conduct electricity and have shiny appearances. However, like nonmetals, metalloids are typically brittle and can behave as semiconductors in terms of their electrical conductivity.
What information is given by the formula of an ionic compound?
The formula of an ionic compound shows the ratio of ions present in the compound. It indicates the types and numbers of atoms involved in forming the compound. The formula does not provide information on the structure or arrangement of the ions within the compound.
How are elments described in terms of their atoms?
How are elements described in terms of their atoms
Are isotopes different in terms of their chemical properties?
A difference of chemical properties is observed for light elements; for other elements these differences are extremely small.
Is francium good?
The terms good or bad are not adequate for chemical elements.
How are elements described in terms of the atoms?
Each chemical element has atoms with a specific number of protons, different from the atoms of other elements.
Which of these terms refers to clouds of dust and gas that are composed of various chemical elements?
Nebulae are clouds of dust and gas that are composed of various chemical elements.
What is terms might be a chemical compound?
A compound contain two or more elements associated by chemical bonds.
In terms of chemical bond and electrons what kind of changes occur between atoms when substances undergo chemical reaction?
hi
What is the appropriate definition for chemical reaction in terms of science?
A chemical reaction is a reaction in which elements have their chemical and/or physical properties altered by the end of the reaction.
Explain chemical changes in terms of the structure and motion of atoms and molecules?
a chemical change destroys the old atoms and molecules to make completely new ones and a completely new substance.
How are atoms of different elements similar and how are they different?
Atoms of different elements are similar in that they all contain protons, neutrons, and electrons. However, they are different in terms of their atomic number (number of protons), atomic mass (sum of protons and neutrons), and electron configuration, which determines their chemical properties.
