Atomic Mass

• Each element found on the periodic table of elements is given an atomic mass

• The atomic mass tells you the average mass of the atoms of an element

• Atomic mass varies from element to element

Atoms

• Atoms of an element are made up of protons, neutrons and electrons

• Protons are found in the nucleus and have a positive charge

• Neutrons are found in the nucleus and have a neutral (no) charge

• Electrons are found outside the nucleus and have a negative charge

Atomic Mass and Atomic Number

• The atomic mass and atomic number for an element on the periodic table can help you determine how many protons, neutrons and electrons an atom of an element has

Finding Protons, Neutrons and Electrons

• Atomic number= the number of protons and the number of electrons in an atom of an element

• Mass number (rounded)= number of protons + number of neutrons (mass of all particles in the nucleus of an atom)

So…

• Oxygen has a total of:– 8 protons– 8 electrons

– 8 neutrons • 15.999 rounded= 16• 16-8=8
