It is important to know about protons (for school level, e.g. GCSE Chemistry) because protons are important for several key topics necessary for the understanding of basic chemistry. These topics include the structure of atoms, isotopes and relative atomic mass....

The quantum mechanical approach is currently used to explain atomic structure. The study of fundamental constituents such as atoms, molecules, substances, metals, crystals, and other aggregates of the matter is where traditional chemistry begins. Let’s now see about some basic terms of chemistry ...
Once the relative mass scale was made, later experiments were able to relate the mass in grams of a substance to the number of atoms and an atomic mass unit—amu was found; 1 amu or Dalton is equal to 1.66×10-24 grams. At this time, chemists knew the atomic masses of elements and...

In chemistry, there are different types of mass. Often, the terms are called weight rather than mass and used interchangeably. A good example is molecular mass or molecular weight. Molecular Mass Definition Molecular mass is a number equal to the sum of theatomic massesof theatomsin amolecule...
Atomic Mass of Iron An element's atomic mass is equal to the sum of the individual particle masses of an atom. Atoms have three basic particles which include protons, neutrons, and electrons. The standard unit for measuring atomic mass is the Dalton (u). ...
In the context of Chemistry, "microscopic" implies detail at the atomic or subatomic levels which cannot be seen directly (even with a microscope!) The macroscopic world is the one we can know by direct observations of physical properties such as mass, volume, etc. The following table provid...
