What is the number of electrons that can occupy the sublevels being filled?
200
These two trends describe electron affinity in the periodic table.
What is electron affinity increasing across a period and decreasing down a group?
200
These are the two terms for positive ions and negative ions.
What are cations and anions?
200
This is the outer electron configuration for a hypothetical element in group 7 and the eighth period.
What is 8s(2)7d(5)?
300
These two questions were derived from Mendeleev's periodic table.
What are the reason for periodicity and why some elements did not follow the increasing atomic mass pattern?
300
This is why the alkali metals are not found free in nature.
What is the fact that alkali metals are very reactive?
300
These are the two periodic trends in atomic radius.
What is the fact that the radius decreases across a period and increases down a group?
300
This is ionization energy.
What is the energy required to remove one electron from a neutral atom of an element?
300
This is the block location of a hypothetical element that has an outer configuration of 5s(2)4d(10)5p(5)
What is the p-block?
400
These three people contributed to the discovery and the addition of the noble gases to the periodic table.
Who are John William Strutt (Lord Rayleigh), Sir William Ramsay, and Friedrick Ernst Dorn?
400
This group is the least reactive group in the periodic table, and the reason for this has to do with chemical bonding.
What is Group 18 or the Noble Gases and why they have eight valence electrons?
400
This is how ions are formed.
What is when atoms gain or lose electrons to achieve a more stable outer configuration?
400
This is the periodic law.
What is the statement that physical and chemical properties of elements are periodic functions of their atomic numbers?
400
This is the outer electron configuration for the group 17 element in the third period, the element it corresponds to's name, and whether it is a metal, nonmetal, or metalloid.
What are 3s(2)3p(5), chlorine, and nonmetal?
500
The examination of the spectra of the 38 different metals by Henry Moseley and Ernest Rutherford discovered this unrecognized pattern which was used in this way.
What is the fact that elements fit into patterns better when they are organized by nuclear charge or the number of protons in the nucleus and the use of the atomic number as the basis for organizing the periodic table?
500
These names are given to Groups 1, 2, 3-12, 17, and 18 on the periodic table.
What are the alkali metals, the alkaline earth metals, the transition metals, the halogens, and the noble gases, respectively?
500

What are electron affinity, electronegativity, ionization energy, atomic radius, and ionic radius?
500
This is electronegativity.
