100
The first element in the Periodic table, and most abundant in the Universe
What is Hydrogen
100
The periodic table is arranged according to this
What is atomic number
100
This man is known as the father of the periodic table
Who is Mendeleev
100
The least reactive group of elements
What is the Noble Gases
100
The names of the rows and columns on the periodic table
What are periods and groups
200
The Noble gas with the atomic number of 36
What is Krypton
200
This value increases as you go up a group and left to right across a period. It is also the liklihood for an element to gain another electron.
What is Electronegativity
200
The periodic table was originally organized this way.
What is increasing atomic mass
200
The group that is most reactive with water
What is Alkali metals
200
The element with the highest melting point of all the elements
What is Tungsten (W)
300
1s22s22p6
What is Neon
300
Atomic radius does this as it goes from left to right across a period
What is decrease
300
This is the man who organized the periodic table based on atomic number
Who is Henry Moseley
300
The name of the family of metals found between the alkali earth metals and metalloids on the periodic table.
What are the transition metals
300
The number of valence electrons Lithium has in its ground state.
What is 1
400
The element that reacts the most vigorously with water in the Alkali metals group
What is Francium
400
The ionic radius of a halogen is larger than that of its ground state for this reason.
What is the element has another electrion, but the same positive force in the nucleus. For this reason the effective nuclear charge increases, increasing the radius.
400
This is the year Uranium was discovered

400
The group of elements that contains Uranium
What is the actinide series
400
The only group on the periodic table to contain solids, liquids and gases
What are the halogens
500
The most normal charge of Zinc
What is +2
500
This is reason atomic radius increases going down a group
What is the effect more electron shells have on the atomic radius
500
The last element to be added to the periodic table
What is Flerovium (Uuq)
500
The name of the group that contains Oxygen
What is the Oxygen family
500
The element that creates compounds harmful to humans. Was commonly used in thermometers before this realization.
What is Mercury
