Electrons in Atoms
True or False: Each element’s spectrum is unique and can be used to determine if that element is part of an unknown compound.
What is True?
The elements in Group 17, made of reactive nonmetals, are called this.
What are halogens?
This is the name of the man who is credited with crafting the periodic table we know today.
Who is Dmitri Mendeleev?
As you go down a group, this happens to the atomic radius.
What is the radius increases?
This is the least electronegative nonmetal.
What is hydrogen (H)?
When an electron drops from an excited state to a lower state, it releases this form of energy.
What is a photon?
Alkaline earth metals have this charge when they become ions.
What is +2 (or 2+)?
Except for hydrogen, every element to the left of the metalloids is this element classification.
What is metal?
True or False: Excluding noble gases & the lanthanides/actinides, the further away you move from fluorine, the less electronegative the element tends to be.
What is True?
This is the official name for ions with a positive overall charge.
What are cations?
These determine the chemical properties of an element. (Be specific.)
What are valence electrons?
(Note: Credit will not be given in this game if this answer is only "electrons.")
This is the group number of the inert gases.
What is Group 18? (OR What is Group 8A?)
(Remember, another name for "noble gases" is "inert gases.")
True or False: The elements in the periodic table are arranged in order of increasing atomic mass.
What is False?
(Usually, mass corresponds to this element arrangement, but not always- especially after considering isotopes. Elements are arranged according to increasing atomic number.)
True or False: As you go to the right across a period, atomic radius decreases.
What is True?
This is Mr. Shepherd's nickname for the bold line indicating metalloids on the periodic table in your reference table packet.
What is the "Semimetal Staircase?"
Matter can have only certain amounts of energy – amounts of energy between these set values do not exist. This term is used to describe energy in atoms, specifically in the electrons with regard to levels.
What is "quantized?"
This property gives the alkali metals the distinction as the "most metal of metals" when it comes to so-called metallic character.
What is a single valence electron? (OR what is only one valence electron?)
Groups 1A-8A are given this name.
(No, it's not the A-Team.)
What are the representative elements?
As you go to the right across a period, excluding noble gases & lanthanides/actinides, ionization energy does this.
What is increases?
This "model" states that electrons act like particles as well as waves of energy.
What is the wave mechanical model?
This is the total number of electrons that would be drawn (whether as a dot, an X, or part of a line) in a complete electron-dot diagram of sulfur dioxide?
What is 18?
(6 from S, 6 from one O, 6 from the other O. You technically don't need to draw the diagram to get this answer; all of those valence electrons count, whether they are in a bond or not.)
This is the full electron configuration of actinium.
What is 2-8-18-32-18-9-2?
(Don't forget the first 2-8-; see note on bottom of page 9)
This is how many elements received new names & symbols after the publishing of your reference table packet in 2011.
What is six?
(Elements 113-118)
This is why noble gases usually don't follow periodic trends.
What is their stability?
This is why water cannot dissolve methane (aka. carbon tetrahydride)?
What is the "like dissolves like" rule?
OR what is methane is nonpolar, whereas water is polar?
