Challenge Questions (x2 Points)
100
The negatively charged smallest particle in the atom.
What is an electron?
100
A part of the periodic table that has elements (like Magnesium) that have two electrons in their valence shell.
What is group two?
100
It will lose two electrons, resulting in having two full electron shells.
What will happen to Magnesium when it reacts with any group six element?
100
A charged particle.
What is an ion?
100
The most reactive non-metal, with seven valence electrons and two electron shells.
What is Fluorine?
200
The model for the atom that we use currently.
What is the quantum cloud model?
200
These gases have a full valence shell, causing them to be the least reactive.
What are noble gases?
200
Electrons are transferred from one to another, causing both atoms to have full valence shells.
What happens when two atoms fully react?
200
The set of electrons in an atom that is farthest from the nucleus.
What is the valence shell?
200
The most reactive metal, with the highest atomic radius of any Alkali Metal and one valence electron.
What is Francium?
300
The force that holds together the protons and neutrons in an atom.
What is nuclear force?
300
This energy decreases as you go down and to the left on the periodic table.
What is the trend for ionization energy?
300
This type of reactivity increases when you go up and to the right of the periodic table.
What is non-metal reactivity?
300
A positively charged particle.
What is a cation?
300
These two atoms both have two valence shells. When reacting, one gives up one electron and loses a shell, and the other fills its valence shell.
What are Sodium and Chlorine?
400
The part of the atom that has neutrons and protons.
What is the nucleus?
400
The distance decreases when you go the right and up on the periodic table.
What is the trend for atomic radius?
400
This reactivity increases when you go down and to the left of the periodic table.
What is metal reactivity?
400
The rule that atoms will give up or take away electrons to have a full valence shell (8 electrons).
What is the octet rule?
400
Two elements in the same column that will react fully with each other, giving them both full valence shells.
What are any two elements with 4 valence electrons?
500
The force that causes atoms to repel and attract each other.
What is electromagnetic force?
500
Metals that make up the middle of the table, including Gold and Silver.
What are transition metals?
500
These non-metals will all fully react with Cesium.
What is a halogen?
500
A set of gases (including Krypton and Xenon) that have a full valence shell and therefore do not react.
What are the noble gases?
500
An element that will react fully with Sodium, resulting in both elements having a full valence shell and 10 total electrons?
What is Fluorine?
