Directions• First get into groups of 3 or 4 students.• Each group needs to print out there own score card found on the next slide.• After printing the score card, click and it will take you to the game board, which is the

periodic table. • First, you click on a lighter colored element (click on the element symbol; i.e., Na) to see the

first question.• Once you answer the question click to find out if you were correct. Keep a tally going of

how many questions you have answered correctly.• On the answer slide, there will be a hint for the answer to the next question. • To find the next question click to take you back to the periodic table. • Once again, click on an element’s symbol. If the hint does not correlate to the question picked

go back to the game board and click on another element to try again. • Try and find the correct element question for each hint.• Write the order of elements on the score card. • Time yourself to see how long it takes to do the scavenger hunt.• The best time with the correct order of elements win.• If a tie occurs, the most number of tallies is the tie breaker.• Note: the button takes you back to the title page.• Start the hunt with the element Hydrogen.

Q - Hydrogen

What is an ion?

Here, a student tries to figure out if sugar water is able to have an electrical current.

A - Hydrogen

An ion is an atom that has a surplus or deficiency of electrons which makes the atom

have a negative or positive charge.

Hint: Ionic bonds have electronegativities above 1.9.

Q - Boron

What is the bond type if the electronegativity is above 1.9?

The student is setting up the experiment to test the electrical current in sugar water.

A - Boron

Ionic bond

Hint:Polar substance dissolve in polar substances

Q - Iodine

True or False, polar substance can dissolve in polar substances.

The student deduces that sugar water cannot have an electrical current.

A - Iodine

True

Hint:A cation has a positive charge.

Q - Calcium

Does a cation have a positive or negative charge?

Here, a student pours salt into water to test salt water’s ability to hold an electric current.

A - Calcium

A cation has a positive charge.

Hint:A non-polar molecule can have polar bonds.

Q - Germanium

Can a non-polar molecule have polar bonds?

Salt water is able to hold an electric current. You can see the effects of the electrical current from the water turning a murky yellow. This color is from the rusting of a nail.

A - Germanium

Yes, a non-polar molecule can have polar bonds.

Hint:Electronegativity is the attraction an atom has for an electron.

Q - Sodium

What is electronegativity?

The student here is pouring sugar into a test tube to analyze the rate at which it melts.

A - Sodium

Electronegativity is the attraction an atom has for an electron.

Hint: Solubility is the ability for a molecule to disassociate into ions.

Q - Carbon

The ability for a molecule to disassociate into ions is called what?

The student holds the sugar over a Bunsen burner to analyze the melting sugar.

A - Carbon

Solubility is the ability for a molecule to disassociate into ions.

Hint:There are two types of covalent bonds.

Q - Lead

How many types of covalent bonds are there?

The student finds that sugar melts very rapidly.

A - Lead

There are 2 types of covalent bonds

HintAn ion can have a negative or positive charge.

Q - Neon

Is an ion neutral?

A student pours salt into a test tube to analyze the rate of melting.

A - Neon

No, an ion is either negative or positive

Hint:The charge of an anion is negative.

Q - Iron

What is the charge of an anion?

The student finds that salt does not melt very fast.

A - Iron

The charge of an anion is negative.

Hint:An ionic bond is formed between the attraction between a

cation and anion.

Q - Chlorine

True or False, an ionic bond is formed from the sharing of electrons between two atoms.

The student here weighs out a certain amount of Benefiber to make slime.

Hint:A non-polar molecule has an electronegativity below 0.4.

Q - Francium

True or False, a non-polar molecule will have an electronegativity below 0.4.

Slime is put onto marks made by different pens and markers to determine if the markers are water soluble like the slime.

A - Francium

True

Hint:The electronegativity of a polar molecule is between 0.5 and 1.9.

Q - Barium

What is the electronegativity of a polar molecule?

It is clearly seen here that two out of four types of markers are water soluble; the blue and red.

A - Barium

The electronegativity of a polar molecule is between 0.5 and 1.9.

Hint:An unequal net pull in a molecule results in a polar molecule.

Q - Aluminum

What does an unequal net pull result in?

These four types of writing utensils, were used to determine their water solubility characteristic. From left to right, a blue high lighter, a red ball point pen, a green expo marker, and a black permanent marker.

A - Aluminum

An unequal net pull in a molecule results in a polar molecule.

Hint:“Like dissolves like” is a term that describes the trend of non-

polar molecules to dissolve in like, or non-polar, molecules, and for polar molecules to dissolve in like, or polar, molecules.

Q - Uranium

Describe the term “like dissolves like.”

Here, the markers and pens are used on a filter paper to determine water solubility.

A - Uranium

“Like dissolves like” is a term that describes the trend of non-polar molecules to dissolve in like, or non-polar, molecules, and for polar

molecules to dissolve in like, or polar, molecules.

Hint:Insolubility is the inability for a molecule to disassociate into

ions.

Q - Rhodium

What does insolubility mean?

Almost immediately after insertion into water, the “wick” brings water to the filter paper, and the water soluble pens and markers start to bleed.

A - Rhodium

Insolubility is the inability for a molecule to disassociate into ions.

Hint:A non-polar molecule can have polar bonds because of the shape of the molecule. If there are two polar bonds that have

equal electronegativity differences and pull in different directions, the overall pull is zero, making the atom non-polar.

Q - Tungsten

Why can a non-polar molecule have polar bonds?

The final design of the filter paper with highlighter and red pen that bled showing that the ball point pen and highlighter are water soluble.

A - Tungsten

A non-polar molecule can have polar bonds. This is because of the shape of the molecule. If there are two polar bonds that have equal

electronegativity differences and pull in different directions, the overall pull is zero,

making the atom non-polar. Hint:

Tungsten is the end of the hunt!
