1. LIST THE THREE PRIMARY PARTICLES IN AN ATOM. DOK 1 The three main subatomic particles that form an atom are protons, neutrons, and electrons. 2. WHERE ARE THE THREE PRIMARY PARTICLES IN AN ATOM LOCATED AND WHAT ARE THEIR CHARGES? 3. EXPLAIN THE RELATIONSHIP BETWEEN THE NUMBER OF PROTONS/ATOMIC NUMBER AND THE POSITION OF AN ELEMENT ON THE PERIODIC TABLE. 4. EXPLAIN THE PURPOSE OF DRAWING ELECTRON DOT DIAGRAMS. DOK 2

Fill in the blanks. The positions of atoms on the periodic table of the ____ are determined by how many _____  are present in their nuclei; this also is called their atomic _____.  An atom's nucleus is made up of protons, which have _____ charges and ___ that do not have a ____charge.  The total of protons and neutrons in an atom defines its atomic ____ .  Two atoms with the same number of protons but different numbers of neutrons in their nuclei are considered _____ . The nucleus is surrounded by electrons, which have  charges.  Electrons are not found randomly, but occur in discrete _____ that are grouped into "shells".  The chemical properties of an atom, that is, the kinds of chemical reactions it has with other atoms or molecules, are determined by properties of its outermost set of orbitals, which is called its _____ shell.  Two atoms will react with each other if the reaction leads to a more stable state; specifically so that their valence shells are ____  .  The most common…

1. explain what happens to an atom when the number of protons, neutrons, or electrons changes, while the number of the other two particles remains the same. 2. Are there different ways to make an oxygen atom?
