9.1 - Natural Radioactivity
Radioactivity: Process by which atoms emit energetic particles or rays
Radiation: The particles or rays emitted (come from the nucleus)
Nuclear Symbols: What we use to designate the nucleus
Atomic Symbol
Atomic Mass
Mass Number
1
, This defines an isotope of boron
In nuclear chemistry often called a nuclide
This is not the only isotope of boron, boron-10 also exists
How many protons and neutrons does boron-10 have?
5 protons and 5 neutrons; mass number is 10 (mass number = protons + neutrons)
Three Isotopes of Carbon
Each nucleus contains the same number of protons
Only the number of neutrons is different
With different numbers of neutrons the mass of each isotope is different
