Name, Oxygen. Symbol, O. Atomic Number, 8. Atomic Mass, 15.999 atomic mass
units. Number of Protons, 8. Number of Neutrons, 8. Number of Electrons, 8.
Since Oxygen's atomic number is 8, it has 8 protons. However, the atomic
number is a not always indicative of how many electrons an atom has, but, for our
Oxygen with the symbol O has the atomic number 8 which means it is the 8th
element in the table. The number eight also means that oxygen has eight protons
All atoms have at least one proton in their core, and the number of protons
determines which kind of element an atom is. For example, an oxygen atom has
Atom, Protons, + Neutrons, = Mass Number. Hydrogen-1, 1, 0, 1. Hydrogen-2, 1,
1, 2. Oxygen-16, 8, 8, 16. Oxygen-17, 8, 9, 17. Oxygen-18, 8, 10, 18. Chlorine-35
Oxygen atoms contain 8 protons and have an atomic number of 8. The atomic
number of an element never changes, meaning that the number of protons in the
The atoms of different elements have different numbers of protons. For example,
all oxygen atoms have 8 protons and all sodium atoms have 11 protons.
