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 best describes the general trend that atomic radius follows on the periodic table.
What is it decreases as you move right in a period and increases as you move down a group?
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 family 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
What is an ION?
An atom with an electron charge
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 d- block and f-block?
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
A positive charge means?
What is a CATION?
300
Ionization energy Trend?
Increases to the right and up
300
The reason the alkali metals are so reactive are because of these 2 properties
What are low ionization energies and electronegativities?
300
Name an element that behaves similar to Lithium?
Any in that same group
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 is being further down in it's group?
400
What do we call the electrons in the outer shell?
What is valence electrons ?
400
Which two elements will make up an ionic compound?
Example : NaCl or similar (ask teacher)
400
What is the electron configuration for Helium?
1s2
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
An example of a covalent compound
Ex: H2O ( ask teacher for clarification?)
