Periods refer to this on the periodic table.
What are rows?
This class of this category are often malleable and can conduct electricity.
What are metals?
What is decreases?
This periodic trend is identifies the amount of force required to remove an electron from an atom.
What is ionization energy?
This element has the highest electronegativity.
What is Fluorine?
The first column on the periodic table contains this family of elements.
What are the alkali metals?
What are nonmetals?
Adding energy levels to an atom does this to its radius.
What is increases its radius?
A larger atomic radius will do this to the ionization energy.
What is decrease ionization energy?
Elements with very low electronegativity will have this type of radius.
What is large?
These elements all have 7 valence electrons.
What are the halogens?
Many of these elements can have more than one ionic charge.
This type of ion is larger than the element.
A huge jump from the first ionization energy to the second ionization energy indicates that the atom is most likely in this family of elements.
What is an alkali metal?
As electronegativity values increase, ionization energy values will generally do this.
What is increase?
Aluminum is this category of element.
What is a metal?
Metals will form these when they become ions.
What are cations?
Between N, O, S and Cl, this atom is the largest.
What is S?
Between Li, F, Na and Cl, this element will have the lowest ionization energy.
What is Na?
Elements in this family do not have electronegativity values.
What are noble gases?
These elements can have the properties of both metals and nonmetals.
What are metalloids?
Each row on the periodic table represents this in the Bohr model of the atom.
What are energy levels?
Between S2-, Ar and Ca2+, this is the largest.
What is S2- ?

If one of these rows represents the ionization energies for Aluminum, it most likely is in the row with this value for first ionization energy.
What is 801?
Metallic character has this relationship to electronegativity.
What is the opposite trend?
