Why do elements in a group have similar chemical

characteristics

A 100

Because they all have the same number of valence

electrons

A 100

What is the gold foil experiment and why what did

it prove.

A 200

Earnest Rutherford shot particles at gold foil and the particles went through the

foil. This experiment demonstrated that atoms are mostly empty space which was a new concept at the

time.

A 200

What is an isotope?

A 300

An atom that has different amounts of neutrons.

A 300

In general, do metals become more or less reactive as you go

down a group?

A 400

Elements generally get more reactive as you go down a

group because there are more electrons shielding the

valence electrons from the nucleus.

A 400

How many protons and neutrons are in an element of Carbon-14?

A 500

6 Protons; 8 neutrons

A 500

What are the three major types of Bonding

B 100

Ionic, Covalent, Metallic

B 100

What is the difference between ionic and covalent bonds in terms of electrons?

B 200

Covalent Bonds – Electrons are shared between atoms

Ionic Bonds – Electrons are transferred from one atom to

another.

B 200

Why do atoms form ions?

B 300

B 300

Because all atoms want to have electron configuration like Noble gases, thus they

will gain or lose electrons in order to become like noble gases.

What types of elements form ionic bonds, covalent bonds

and metallic bonds?

B 400

Ionic – Metal and Non-metal, or metal and Polyatomic ion

Covalent – Non-metal and Non-metal

Metallic – Metal and Metal

B 400

What are characteristics of ionic substances?

B 500

High melting and boiling points

Dissolve readily in water and conduct electricity

Brittle Solids

B 500

What are some signs of a chemical reaction?

C 100

C 100

Bubbling, Color Change,

Precipitate, Temperature

Change

C 200

What is the law of conservation of

mass?

Matter cannot be created or destroyed. We must have a balanced chemical equation.

C 200

What is the mole ratio and where is it found?

C 300

The mole ratio related the amount of one substance to

the amount of another substance in the chemical

reaction. It can be found in a balanced chemical equation.

Place A Wager

Solve the stoichiometry problem Ms. Jensen is putting

on the board.

C 400

Ms. Jensen will determine if you are correct.

C 400

Define endothermic and exothermic reactions.

C 500

Exothermic reactions are reactions where energy is a released, ∆H is negative and

reactions generally feel warm.

Endothermic reactions are reactions where energy is

absorbed, ∆H is positive and reactions generally feel cold.

C 500

What are the four major factors that effect the rate of a

chemical reaction

D 100

Temperature

Surface Area

Concentration

Catalysts

D 100

What is an effective collision?

D 200

A collision where molecules have the right speed and

angles in order to create a reaction.

D 200

What is equilibrium?

D 300

A state at which a reactions forwards reaction rate equals

the reverse reaction rate. Products and reactants are being produced in equal

amounts.

D 300

How does adding more reactants effect the

equilibrium in a reaction?

D 400

If you add more reactant the equilibrium will shift right in

order to reestablish equilibrium according to Le

Chateliers Principle.

D 400

Which way will an endothermic reaction shift if we decrease the temperature?

D 500

The reaction will shift left to reestablish equilibrium.

D 500

What is the solute?

E 100

The substance that is dissolved in the solvent.

E 100

What are the units of Molarity and molality?

E 200

Molarity – moles of solute/liters of solution

Molality – moles of solute/kg of solvent

E 200

What are the three colligative properties?

E 300

Vapor Pressure Decreasing

Boiling Point Elevation

Freezing Point Depression

E 300

.

E 400

Which will lower the freezing point the most

and why?NaCl or C6H12O6

NaCl, because it dissociates into two particles and will

hold solvent particles in the liquid more effectively that

molecular substances that do not dissociate.

E 400

Name two instances where colligative properties are used in

everyday life.

E 500

Road Salt

Anti-Freeze in cars

Other responses will be judged by Ms. Jensen

E 500

F 100

What makes a substance an acid?

The ability to dissociate into H+ ions.

F 100

What is an acid on the pH scale?

F 200

Anything lower than 7.

F 200

What is the [OH-] in a neutral solution?

F 300

1 x10-7

F 300

Calculate the molarity of HCl if 20.0 mL of it are needed to neutralize 34.0 mL of a 0.90

M NaOH solution.

F 400

1.53 M

F 400

What is the most massive type of radiactive decay?

F 500

Alpha particles
