What is a chemical bond?
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
In a chemical formula the positive ion is always written ____________

200
An ionic bond consists between a ______ and a ______
What is a metal and a non-metal?
200
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 ionic radius?
200
These elements located in the ______ family have the highest ionization energies.
What are the Noble gases?
200
Name this compound: Ti2(SO3)3
What is a titanium (III) sulfite?
300
What type of bond occurs when atoms share electrons?
What is a covalent bond?
300
Generally as ionization energy goes across a period, does it increase or decrease? Why?
Across a period, it increases b/c the effective nuclear charge holds the electrons more tightly.
300

400
You are given a mysterious compound and you have to determine if it is ionic or covalent. The substance as a solid does not conduct electricity, however, when dissolved in water, it acts as a good conductor. Which of the following substances could it possibly be: NH3, HClO3, CoCl2?
What is CoCl2?
400
Magnesium ion is smaller than Calcium ion for this reason
Less energy levels
400
As we move up a group on the periodic table the ionization energy increases for this reason
What is due to the fact that the valence electrons are closer to the nucleus; effective nuclear charge; smaller ionic radius
400
