Geography 1
go left to right on a periodic table and tell us the number of electron shells there are in an atom
What is "a period"?
go up and down on a periodic table and tell us the number of valence electrons an atom has
What is a "group"?
the amount of energy required to remove an electron from an atom
What is "ionization energy"?
the measure of an atom's ability to attract electrons from another atom to form a bond
What is "electronegativity"?
The electron configuration for the most metallic element on the periodic table
What is "2-8-18-8-1 (for Cs)"?
the very reactive elements in Group 1 are known as this
What is "alkali metals"?
the very reactive nonmetals in Group 17 are known as this
What is "halogens"?
These trends are a result of Groups 1 and 2 losing electrons easily to form octets.
What is "ionization energy and electronegativity"?
Which is larger, Li+ or Cl-, and why?
What is "Cl- because it has more electron shells"?
the most electronegative element on the periodic table
What is "fluorine"?
the names of the metals in the F block
What is "Lanthanides and Actinides"?
What are the three (3) types of elements on the periodic table?
What is "metals, nonmetals, and metalloids"?
the reason why noble gases are stable and not reactive
What is "a full outer electron shell"?
**Daily Double** the two (2) reasons for why we see trends on the periodic table
What is "nuclear charge and number of electron shells"?
the two most reactive elements on the periodic table
What is "Cs and F"?
the scientist who first organized the periodic table by atomic number
Who is "Mendeleev"?
What type of element gains electrons to get a full octet?
What is "nonmetals"?
Which atom is larger, S or Po, and why?
What is "Po because it has more electron shells"?
Which element has the higher ionization energy, Sr or Te, and why?
What is "Te because it is a smaller atom, so its electrons are close to the nucleus and tightly held onto; takes a lot of energy to remove an electron"?
the properties of metals (5)
What is "good conductors of heat and electricity, lustrous, malleable, ductile, and lose electrons to form ions"?
The name for unknown element X, which forms the ionic compound X3N and has a first ionization energy in the 400s.
What is potassium (K) ?
these six (6) elements have properties of metals and nonmetals
What is "Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium"?
two (2) trends that are inverses of each other
What is "atomic radius/ionic radius and electronegativity/metallic character"?
What is "(smallest) Ra, Ca, Fe, Si (largest)"?
the definition of periodic law
What is "when elements are organized by atomic number, there is a repeating pattern of chemical properties"?
