Miss Hamilton's Notes:

So by now most of us should have learned the following in class on Chapter 17 - Atomic Structure and the Periodic Table:

-Atoms are indivsible and indestructible and are made out of protons, neutrons, and electrons
-Protons are positively charged and are located in the nucleus along with neutrally charged neutrons
-Electrons are located in the electron cloud that surrounds the nucleus of an atom and are negatively charged.
-Atoms are neutral because the positively charged nucleus and negatively charged electron cloud "cancel out" each other
-Protons and Neutrons both equal 1 AMU (atomic mass unit) and therefore have the same mass
-Electrons are much smaller than protons and neutrons (1 electron = 1/2000 proton)
-The nucleus makes up most of the mass, the electron cloud makes up most of the volume
-Atomic number (top of periodic table block) is the number of protons
-Atomic mass (mass, in amu's) of the atom
-Mass number = total # of protons and neutrons (# n = mass # - # p or atomic number)
-# protons = # electrons

E.Q. # 16

Where is the marjority of the mass located in an atom? What are the two subatomic particles that make up this area?
