Fat Alberts & Planktons 300 How do you determine the number of protons in an atom? Answer: The atomic number
Fat Alberts & Planktons 400 How many electrons does calcium have in its outer orbit? Answer: 2
Fat Alberts & Planktons In ionic compounds, which ion is responsible for the colorful spectra you see? Answer: Positive Ion
Fat Alberts & Planktons The nucleus of an atom consists of: Answer: Protons
Tables 100 What does the row number an element is in tell us about the element? Answer: The number of orbits (shells) an atom has
Tables On top of each column, there is a family or group number. What does the group number of an element tell us about the element? Answer: The number of valence electrons
Tables 300 The property that describes the ability of an atom to attract electrons Answer: Electronegativity
Tables 400 Molecules that share electrons, but not equally are called Answer: polar covalent
Tables 500 Molcules that share electrons with water equally and DO NOT mix with water are Answer: nonpolar covalent
Tables 600 The part or section of the molecule that demonstrates both positive and negative charges (but can still be overall neutral) is a(n) Answer: dipole
The Atom The outermost electrons in an atom are called _______________ electrons. Answer: Valence
The Atom In the compound KCl, which element creates a positive ion? _______________ Answer: K (Potassium)
The Atom In the compound CaCl2, which element creates a negative ion? _______________ Answer: Cl (Chlorine)
The Atom 400 Which bond has the most drastic difference in electronegativity values? Answer: ionic
The Atom 500 How many electrons are needed to satisfy the Octet Rule? ________ Answer: 8
The Atom 600 Are there any exceptions to the Octet Rule? If so, what are they? Answer: Yes, hydrogen and helium
Miss Alanious What kind of spectra is produced by an incandescent light bulb? ______________ Answer: Continuous light spectra
Miss Alanious 200 What two things did Rutherford discover in his experiments? ________________ Answer: The nucleus and the atom was mostly empty space.
Miss Alanious What causes elements to emit certain colors when viewed through a spectroscope? Answer: The excitement of electrons which move them to higher orbits. When electrons return to their “ground state” a photon of light is released.
Miss Alanious Draw a labeled diagram of the “Bohr Model” for a neutral atom of Lithium (Li). Include all the basic particles in their proper locations. Answer:
Miss Alanious Describe the Rutherford experiments. What did he do to discover what he discovered? Answer: The experiment shot alpha particles at gold foil counting the number of particles that passed through and repelled from the gold foil. Rutherford discovered the atom’s nucleus and that the atom was made up of mostly empty space.
Miss Alanious 600 Why do positive ions attract to negative ions? What type of bonds do they form? Answer: Ions attract because they are opposite charges and they form ionic bonds
Final Jeopardy What did the Bohr model help to explain that the Rutherford model did not? Answer The Bohr Model explained that electrons exist in orbits outside the nucleus and become excited because of energy and release different colors (photons) of light.
