CATEGORY 1 - $100 This atomic particle determines chemical behavior

CATEGORY 1 - $100 What are electrons?

CATEGORY 1 - $200 How many electrons fill the first three energy levels in an atom?

CATEGORY 1 - $

CATEGORY 1 - $300 The periodic table shows that Aluminum has 14 of what?

CATEGORY 1 - $300 What are neutrons?

CATEGORY 1 - $400 All atoms have a nucleus made of protons and neutrons, and electrons outside the nucleus in an electron cloud. This describes what?

CATEGORY 1 - $400 What do atoms of different elements alike? - Basic atomic structure

CATEGORY 1 - $500 This is the sum of protons and neutrons

CATEGORY 1 - $500 What is the atomic mass?

CATEGORY 2 - $100 This is what atoms do in order to fill their valence electron level.

CATEGORY 2 - $100 Why do atoms bond with other atoms?

CATEGORY 2 - $200 This bond has oppositely charged particles attracted to each other

CATEGORY 2 - $200 What is an ionic bond?

CATEGORY 2 - $300 In this bond, electrons are not shared evenly around the molecule

CATEGORY 2 - $300 What is a polar (covalent) bond)

CATEGORY 2 - $400 In this process, chemical bonds break and new bonds form as atoms are rearranged to form new substances

CATEGORY 2 - $400 What happens in a chemical reaction?

CATEGORY 2 - $500 This bond forms when both atoms need more electrons to fill their valence levels.

CATEGORY 2 - $500 When do covalent bonds form?

CATEGORY 3 - $100 This describes the water molecule because the oxygen end of water has a partial negative charge and the hydrogen end has a partial positive charge.

CATEGORY 3 - $100 Why is water a polar molecule?

CATEGORY 3 - $200 This is the property caused when hydrogen bonds pull water molecules together

CATEGORY 3 - $200 What is cohesion?

CATEGORY 3 - $300 High surface tension and high heat capacity are caused by this behavior of water

CATEGORY 3 - $300 What is cohesion?

CATEGORY 3 - $400 Water will dissolve most substances needed by cells because of this property.

CATEGORY 3 - $400 What is adhesion?

CATEGORY 3 - $500 Water uses both cohesion and adhesion for this property important to plants and animals.

CATEGORY 3 - $500 What is capillary action?

CATEGORY 4 - $100 This is the main component in a liquid mixture.

CATEGORY 4 - $100 What is solvent?

CATEGORY 4 - $200 This is what pH measures in a solution.

CATEGORY 4 - $200 What is hydrogen ion concentration?

CATEGORY 4 - $300 In a neutralization reaction, an acid plus a base will yield water plus this substance.

CATEGORY 4 - $300 What is a salt?

CATEGORY 4 - $400 In this type of substance, chemical bonds do not break when it dissolves in water.

CATEGORY 4 - $400 What is a molecule? (covalently bonded)

CATEGORY 4 - $500 A solution of pH 4 has a higher concentration of hydrogen ions than a solution of pH 6, by a factor of this much.

CATEGORY 4 - $500 What is 100 times

CATEGORY 5 - $100 This is how long it will take ½ of a radioactive substance to decay to a stable form.

CATEGORY 5 - $100 What is “half life”?

CATEGORY 5 - $200 We use this for dating fossils and for tracing the path of elements in biologic processes.

CATEGORY 5 - $200 What is radioactive carbon? (carbon 14)

CATEGORY 5 - $300 Water on the surface of our skin will cool the body because it does this.

CATEGORY 5 - $300 What is evaporate?

CATEGORY 5 - $400 Elements bonded ionically always form this shape.

CATEGORY 5 - $400 What is a crystal (lattice)?

CATEGORY 5 - $500 In a PET scan, a radioactive isotope is injected into a person to show this.

CATEGORY 5 - $500 What is rate of tissue function? (activity level, isotope uptake)
