200
Fluorine is the first element in this group (name, not number).
What is the halogen group?
200
These elements have low melting and boiling points, in fact, many are gases at room temperature.
What are nonmetals?
200
Between Carbon, Nitrogen and Oxygen, this element has the largest atomic radius.
What is Carbon? (Radius decreases from left to right and increases from top to bottom)
200
The oxidation number for Aluminum.
What is +3?
200
These compounds have high melting and boiling points.
What are ionic compounds?
300
This group contains elements that are pretty reactive with water and air. They lose two electrons to become cations. What is their name and number?
What are the alkaline earth metals, group 2?
300
As you move down the periodic table, reactivity increases. This element is the most reactive element of all.
What is Francium?
300
The period number corresponds to this property of atoms. (Think about Bohr models.)
What is the number of energy levels. (Period number equals the number of energy levels in the atom.)
300
The oxidation number is the same thing as ______.
What is charge?
300
This is the reason most elements will bond with other elements.
What is elements want a full octet in their outermost energy level, this means most elements want 8 valence electrons.
400
Elements in this group are mostly unreactive, they are stable. What is their group name and number?
What are the noble gases, group 18?
400
This element is considered to have the smallest atomic radius. Radius decreases as you move from left to right on the table.
What is Helium?
400
Out of Magnesium, Calcium and Strontium, this element is the smallest (smallest radius).
What is Magnesium? (Radius increases as you go from top to bottom of the table)
