Final Jeopardy
$100 Question from H1
This person is credited with creating the first periodic table.
$100 Answer from H1
Dmitri Mendeleev
$200 Question from H1
This person made a list of the knownelements at his time.
$200 Answer from H1
Antoine Lavoisier
$300 Question from H1
This is how we order the periodictable today.
$300 Answer from H1
Increasing atomic number
$400 Question from H1
This is how Mendeleev arranged hisPeriodic Table.
$400 Answer from H1
Increasing atomic mass
$500 Question from H1
This is why Mendeleev left blankson his periodic table.
$500 Answer from H1
To represent elements that hadn’t yet been discovered.
$100 Question from H2
This is the least reactive group.
$100 Answer from H2
Noble Gases
$200 Question from H2
These are the two most reactive groups
$200 Answer from H2
Alkali metals and Halogens
$300 Question from H2
This is the same for all of the elementsin the same group.
$300 Answer from H2
Number of valence electrons
$400 Question from H2
This group of metals are slightly less reactive than alkali metals.
$400 Answer from H2
Alkaline earth metals
$500 Question from H2
This group has one electron intheir outermost s orbital.
$500 Answer from H2
Alkali Metals
$100 Question from H3
This element has the smallest atomic radius.
$100 Answer from H3
helium
$200 Question from H3
Ionization energy is the energy neededto remove this.
$200 Answer from H3
An electron
$300 Question from H3
This is what happens to electronegativity when you moveright in a period.
$300 Answer from H3
It increases.
$400 Question from H3
This is how ionization energy changesmoving down a group.
$400 Answer from H3
It decreases.
$500 Question from H3
This period 3 nonmetal has thelargest atomic radius.
$500 Answer from H3
phosphorus
$100 Question from H4
This divides the metals and nonmetals on the periodic table.
$100 Answer from H4
Stair-step line
$200 Question from H4
These are found next to the stair-step line.
$200 Answer from H4
metalloids
$300 Question from H4
These are found to the right of thestair-step line.
$300 Answer from H4
nonmetals
$400 Question from H4
These are good conductors of heat.
$400 Answer from H4
metals
$500 Question from H4
This element on the stair-step line isn’t a metalloid. It is a metal.
$500 Answer from H4
aluminum
$100 Question from H5
This is gained or lost when an atombecomes an ion.
$100 Answer from H5
electrons
$200 Question from H5
This is the reason atoms become ions.
$200 Answer from H5
To obtain a full valence shell (8)
$300 Question from H5
This is the term for a positive ion.
$300 Answer from H5
cation
$400 Question from H5
This is the term for a negative ion.
$400 Answer from H5
anion
$500 Question from H5
This is what happens to the size of anatom when it becomes a cation.
$500 Answer from H5
It decreases.
Final Jeopardy
Provide the explanation for the group and period trends for atomic radius.
Final Jeopardy AnswerThey increase down a group because each row adds an electronshell.
They decrease in a period because Each proton draws electrons closer.
