The data in ____________ show that _______________________________ have about the same _________. The masses of an atom’s electrons are negligible (doesn’t count) compared to an __________________. An atom’s ______________ and _____________ are packed tightly _____________________________. Visualize the nucleus as the size of an ________. How large would the atom be? ____________________________________ 7) Atomic Number …page 195 The number of _______________ in an atom of an _______________ is the element’s __________________________________ Read Page 197-198 for #8 and #9 #8 Define isotope…… #9 Define mass number (also called the atomic mass) #10 Read Democritus and the Atom on page 176 Greek Philosopher ________________ was the first person to ___________________________. ________ comes from the greek word atoma which means “_____________________.” Indivisible describes something that ___________________________________________. #11 Read the last paragraph for the Democritus and the Atom section and explain how the student in figure 3 is illustrating Democritus’s experiment. 12) Define Atomic Mass Number on page 197 13) Figure 24 on page 193 Write a brief description of each 14) Page 196 Atomic Number and the Periodic Table section The atomic mass is the average mass of all the _______________________ of an ____________________________ Dalton’s Model of Atom: ____________________________________________________ Thomson’s Model: _________________________________________________________ Rutherford’s Model: ________________________________________________________ Bohr’s Model: _____________________________________________________________ Electron Cloud Model: ______________________________________________________ Elements in the periodic table are arranged _________________ in order of ___________________________________________. The elements are also arranged _____________ in groups with similar __________________________. #15) Page 196 Atomic Number and the Periodic Table section 16) Figure 26 on page 196 17) BACK COVER OF TEXTBOOK (PERIODIC TABLE) #18 BACK COVER OF TEXTBOOK (PERIODIC TABLE) Where are the SYNTHETIC elements mostly located on the Periodic Table? # BACK COVER OF TEXTBOOK (PERIODIC TABLE) In figure 26, the blocks for most of the elements are _________________________. These elements are __________. The blocks for ______________ are ____________. Between the metals and the nonmetals are the _________________. These elements are represented by the _______________________________. Semimetals are elements that have properties similar to ________________________________________________________. List a few elements that seem familiar to you: __________________________________ Name a few elements that you’ve never heard of before: _______________________________________________________________________ The horizontal ROWS are called ___________________. The vertical COLUMNS are called ______________. Elements in the same group have ________________________________________________________________________. They are mostly located _____________________________________________________ If oxygen has an atomic number of 8 then what is the atomic number for gold? __________ #20 BACK COVER OF TEXTBOOK (PERIODIC TABLE) If helium has an atomic mass of 4.0026 then sodium has an atomic mass of ____________ #21 BACK COVER OF TEXTBOOK (PERIODIC TABLE) The chemical symbol (sometimes called the element symbol) for beryllium is Be. What is the chemical symbol for Chlorine? ____________________ #22 Read BACK COVER OF TEXTBOOK (PERIODIC TABLE) The period that the element sodium is in is _______________ The period that the element krypton is in is _______________ The family or group that the element bromine is in is _______________ The family or group that the element nickel is in is _____________ #23 Fill in the information for each element using the periodic table on page 134 and 135. Note each element’s square tells us the atomic number, chemical symbol, chemical name, and the atomic mass. 29 33 _________ Cu ____ ____ _________________ Arsenic _________________ 63.546 ___________ 137.33
