100
The criterion that John Newlands used when he put together his version of the periodic table.
What is the atomic mass.
100
This family of elements were once considered inert because they rarely react with any other elements.
What are the noble gases.
100
These elements are poor conductors of heat and electricity.
What are nonmetals.
100
This type of ion tends to be larger than the parent atom.
What is an anion.
100
The name for a row on the periodic table.
What is a period.
200
The scientist that used his periodic table to predict the properties of elements that had not yet been discovered.
Who is Dmitri Mendeleev.
200
This family of elements is so reactive that they must be stored under mineral oil to prevent them from reacting with the air or water.
What are the alkali metals.
200
This type of element makes up the majority of elements on the periodic table.
What are metals.
200
Atoms with the largest atomic radius are located in this corner of the periodic table.
What is the bottom left corner.
200
This is the name for a column on the periodic table.
What is a group or family.
300
This scientist named the Law of Octaves.
Who is John Newlands.
300
These elements are the most reactive nonmetals on the periodic table, and tend to react with metals to form salts.
What are halogens.
300
These elements have properties of both metals and nonmetals.
What are metalloids.
300
Atoms with the highest ionization energy are located in this corner of the periodic table.
What is the top right corner.
300
The term for the outermost energy level of electrons in an atom.
What is the valence shell.
400
Henry Mosley organized the modern periodic table according to this criterion.
What is atomic number.
400
These elements make up the d-block on the periodic table, and are less reactive than the alkali metals.
What are the transition metals.
400
These elements are found along the staircase of the periodic table.
What are metalloids.
400
This element has the highest electronegativity of all elements on the periodic table.
What is fluorine.
400
The number of valence electrons present in an atom of tin.
What is four.
500
Which scientist's periodic table had discrepancies when arranged by atomic mass?
Who is Dmitri Mendeleev.
500
This family is unique in that the nuclear structure of these elements is more important than the electronic (electron) structure.
What are the actinides.
500
This type of element consists of cations bound together by a sea of loosely held valence electrons.
What are metals.
500
This metal is the most reactive metal on the periodic table.
What is francium.
