Periodic Table
The names of the first 2 groups of the periodic table
What are Alkali Metals and Alkaline Earth Metals?
The unit of measure for atomic radius
What is the angstrom?
Ionization energy
What is the energy it takes to remove an electron from an atom?
the amount of energy that is released when an electron is added to the ground-state of a gaseous atom.
What is electron affinity?
The person who discovered electronegativity
Who is Linus Pauling?
The periodic table was originally organized by ----- and is now organized by ------
What is atomic mass and atomic number?
The atomic radius of elements as they move from left to right on the periodic table
What is decreasing?
The number of valence electrons in Selenium (Se).
What is 6?
A group of elements that do not release energy when an electron is added to them.
What are the noble gasses?
Electronegativity
What is the measure of how strongly the atoms attract electrons that are shared between atoms in a molecule.
The cyclical patterns of common physical or chemical traits
What are periodicities?
The ionic radius when S ionizes to S2-
What is increases?
Ion formed when an atom loses an electron.
What is a Cation?
The trend for electron affinity
What is increasing from left to right as you move across the period, and decreasing from top to bottom?
The trend for electronegativity
What is increasing from left to right and decreasing from top to bottom?
The groups on the periodic table that are considered non-metals
What are the chalcogens, halogens, and noble gasses.
Adding an additional shell at the beginning of each period (S block).
What is increasing the atomic radius?
The trend for ionization energy
What is increasing from left to right and decreasing top to bottom?
The groups on the periodic table that have the highest electron affinity (want to gain electrons)
What are groups 15,16,17 (non metals)?
The element with a higher electronegativity than oxygen.
What is Florine?
Ions that are formed by metals and non metals.
What are cations and anions?
When more core electrons are present in an atom, reducing the attraction between the positive nucleus and the valence electrons.
What is the shield effect?
Why it is more difficult to remove an electron from Chlorine (Cl) than Sodium (Na).
What is an increase in electron/proton attraction?
The types of ions the elements will most likely form, and the charge they acquire.
What is the oxidation state?
The correct order from lowest to highest electronegativity
K, Si, Cl, Na, Mg, F
What is
K, Na, Mg, Si, Cl, F
