Was the first to group elements by similar characteristic, but his periodic table had many blank spaces.
What is Mendeleev?
100
The period on the periodic table represents this portion of the electron configuration.
What is the energy level of the valence electrons?
100
One-half the distance between the nuclei of identical atoms bonded together.
What is atomic radii?
100
These two series of elements very rarely follow any trends.

S-block elements are reactive members of which category of elements.
What is metals?
200
An atom or group of bonded atoms that has a positive or negative charge.

These are referred to as the "main-group" elements.
What are the s- and p-block?
400
The energy change when a neutral atom gains an electron.
What is electron affinity?

500
The repeating pattern found within the periodic table.
What is periodicity?
500
An element has the electron configuration: [Ar](3d8)(4s2). It is found in this period, group, and block.
What is fourth period, d-block, and Group 10.
500
The measure of an atoms ability to attract electrons.
