4.1-----------------------------------------------------------------------------------------------------------------------------Understand Dalton’s Atomic Theory and list the 3 major details
1. _____________________________________________________________________________________
2. _____________________________________________________________________________________
3. _____________________________________________________________________________________
Name the dense central region of the atom ______________________________
Describe the 3 subatomic particles in terms of location and charge
1. Proton Location:_______________________________Proton Charge:____________________________
2. Neutron Location:______________________________Neutron Charge:__________________________
3. Electron Location:______________________________Electron Charge:__________________________
Use the periodic table to describe atom types in terms of #’s of protons and e-s
Ar has __________________ protons and _____________________electrons
Understand the Bohr model of the atom and what the symbols represent
The Bohr circles represent _________________________________________________________________
The Bohr dots represent ___________________________________________________________________
Define Valence electrons__________________________________________________________________
Draw a Bohr model of one of the first 18 elements and identify the valence electrons
4.2-----------------------------------------------------------------------------------------------------------------------------The elements are arranged on the periodic table according to their numbers of __________________.
Chemical families have similar ___________characteristics because they have the same ______________.
Define ion______________________________________________________________________________
Atoms become ions by ____________________________________________________________________
Define isotope __________________________________________________________________________
Atomic number _________________________________________________________________________
Mass number ___________________________________________________________________________
Describe C-14 atoms in terms of subatomic particles: # protons_______ #e-________ # neutrons_______
4.3--------------------------------------------------------------------------------------------------------------------------Use the periodic table sketch below to label the 4 chemical families discussed in class
Label where the metals, transition metals, and the non-metals are located on the periodic table
Across the period, as the number of valence electrons (increases/decreases), reactivity (increases/decreases).
4.4---------------------------------------------------------------------------------------------------------------------------Tell what a mole describes and how Avogadro’s number is related to a mole
Define molar mass and know how to find it on the periodic table
Use unit analysis to convert from moles to grams and from grams to moles
