Atomic Symbols, Atomic Numbers, and Mass Numbers. In this interactive object, learners calculate formula and molecular weights by working through five examples and two problems. Students examine atomic structure and the octet rule.
The number of protons in an atom is known as the Atomic Number, which is how the periodic table is organized (they are listed in order of atomic number from left to right). The Mass Number describes the total number of protons and neutrons in the nucleus.
No two elements have the same atomic number; therefore, elements can be identified by their atomic numbers. Elements are also identified by a unique chemical symbol that contains one or two letters to identify them. For example, the chemical symbol for oxygen is, and the chemical symbol for copper is .
Beneath the element symbol is the atomic mass. Atomic mass is measured in Atomic Mass Units where 1 amu = (1/12) mass of carbon measured in grams. The atomic mass number is equal to the number of protons plus neutrons, which provides the average weight of all isotopes of any given element.
Its mass is on average u in terrestrial samples. (b) The symbol may, as a kind of shorthand, denote a sample of the element. For example, Fe can denote a sample of iron, and He a sample of helium gas. The term nuclide implies an atom of specified atomic number (proton number) and mass number (nucleon number).

Rules for chemical formulas (Back to search) To specify any number (including zero) of given element, use an asterisk (*) after the element symbol. To explicitly specify an ion, place the charge at the end of the formula. If the charge is greater than one the charge should be included after the + or .
Atomic number, atomic mass. The number of neutrons in a given element, however, can vary. The variants of the same chemical element with a different number of neutrons are called isotopes. Protons and neutrons determine the mass of an atom. Mass number .
oxygen atomic number 8 symbol O. carbon atomic number 6 symbol C, hydrogen atomic number 1 symbol H. nitrogen atomic number 7 symbol N.

atomic mass (symbol: ma), which is the mass of a single atom, commonly expressed in unified atomic mass units. relative atomic mass (symbol: Ar, also called atomic weight), which is the ratio of the average mass per atom of an element from a given sample to 1/12 the mass of a carbon12 atom.
