Definition Oxygen is a chemical element with atomic number 8, represented by the symbol O. The name oxygen was coined in 1777 by Lavoisier. Its name derives from the Greek word "oxys" meaning "sharp," referring to the sharp taste of acids, and "gen膿s" meaning "producer." It is a ...
Mass number is not shown on the periodic table but is often found when elements are shown as symbol-mass number (such as oxygen-16). What is the difference between atomic mass and atomic number? Atomic mass is the average weighted mass number of all isotopes of a given element. It is ...

Atomic Number • Hydrogen has one proton in the nucleus, and 1 electron around its nucleus. • Oxygen has eight protons in the nucleus, and eight electrons around its nucleus. Mass Number • Mass number is made up of the total number of ...
Atomic Number Examples All elements on the periodic table have an identifying atomic number. Here are a few atomic number examples: Hydrogen - atomic number 1. Carbon - atomic number 6. Oxygen - atomic number 8. Sulfur - atomic number 16. Gold - atomic number 79. Fermium - atomic number ...
An Isotope is an element that has the same number of protons and electrons but a different number of neutrons in its nucleus. A given atom’s atomic number is always equal to its number of protons. Because oxygen has an atomic number of 8, the total number of protons in an oxygen ato...
