A Period in History
I'm Keeping my Ion You
So You Think You Can Take my Electron
Chemicals Don't Reason, they "React"
I Should Have been in a Different "Family"
100
These scientists were the first to come up with a way to arrange the elements on the periodic table
Who is Lothar Meyer and Dmitri Mendeleev?
100
This is the trend that explains the size of an atom
What is it atomic radius?
100
The amount of energy required to remove an electron from an element.
What is the ionization energy?
100
This particle is responsible for chemical bonding.
What is the electron?
100
A group is the same as this on the periodic table
What is a vertical column?
200
This British Scientist re-arranged the Periodic Table to better fit each elements reactivity, in fact our modern periodic table is based on his work
Who is Henry Mosley?
200
All ions will lose or gain enough electrons to have a noble gas configuration
What is the octet rule?
200
These elements have the highest ionization energies.
What are the Noble gases?
200
The most reactive non-metals on the periodic table belong to this group
What are the halogens?
200
These elements are known for their unique colors and multiple oxidation states.
What are the Transition Elements?
300
This property was first used to arrange the Periodic Table of the elements
What is the atomic mass?
300
This particular property of elements can be used to explain why cations get smaller when they form ions and why anions are larger when they form ions.
What is net charge?
300
The alkaline earth metals experience a significant increase in ionisation energy.
What happens on the third ionisation energy?
300
The reason the alkali metals are so reactive are because of these 2 properties
What are low ionization energies and electronegativities?
300
These elements react to form volatile oxides and they react quite violently when placed in water!
What are the alkali metals?
400
This property is what is now used to arrange the elements on the periodic table.
What is the atomic number?
400
Magnesium ion is smaller than Calcium ion for this reason
What happens to ionic size when you go down a group?
400
As we move up a group on the periodic table the ionization energy increases for this reason
What happens when the valence shell moves closer to the nucleus?
400
This trend increases as you move left and down the periodic table
What is the trend of metallic character?
400
Elements that belong in a group have these three particular things in common.
What are chemical properties, physical properties, and similar electron configurations?
500
Several of the elements would have to be rearranged on the periodic table if it were still based on atomic mass. Give 3 examples of elements that would need to be rearranged.
What are K and Ar, Te and I, and U and Np?
500
You do not have to answer this in the form of a question. Please arrange the following elements based on increasing ionic size: Strontium Ion, Bromide, Selenide, and Rubidium Ion. Please give the correct symbols and charges
Sr 2+, Rb 1+, Br 1-, and Se 2-
500
You do not have to answer this in the form of a question. Please arrange the following elements based on decreasing ionization energy: Gallium, Krypton, Calcium and Arsenic
Krypton, Arsenic, Calcium, and Gallium
500
Do not answer this in the form of a question. Arrange the following elements based on increasing non-metallic character: Chlorine, Oxygen, Fluorine, and Sulfur
Sulfur, Chlorine, Oxygen, and Fluorine
500
Elements in this family are most likely to gain 2 electrons to fill their valence shell.
What are the Chalcogens?
