An atomic nucleus can be described by the analogy “like a marble in the Dallas Cowboys Stadium.” If a marble represents the atomic nucleus, what does the stadium represent?
What subatomic particle do all Carbon atoms, isotopes and ions have in common?
What if there are a different number of Neutrons?
Sometimes elements have a different number of neutrons than usual, so therefore have a different atomic mass. This is what we call an Isotope (a variant form of an element which has the same number of protons but a differing number of neutrons).
Sometimes we’ll see Isotopes labeled with their new mass like this:
14C = this is Carbon 14. Notice it has a different mass than what is on your periodic table
The average mass of all the isotopes is defined as an element’s Atomic Weight. Can you answer questions about these Isotopes?

The specific isotopes used depends on the particular organ or body system being studied (for example, Xe-133 is used to image lung function and blood flow.)

The most common one, 210Po, has 82 protons and 128 neutrons. When 210Po decays, it emits an alpha particle, which is a helium nucleus (2 protons and 2 neutrons). 210Po decay is tricky to detect because alpha particles do not carry very much energy compared to other forms of radiation. For example, they can be stopped by a single sheet of paper or a few inches of air. That is one reason that authorities failed to discover toxic amounts of 210Po in the body of former KGB agent Alexander Litvinenko until after he died suddenly and mysteriously in 2006. What element does an atom of 210Po become after it emits an alpha particle?arrow_forward
