WGU - Chemistry Terms

QuestionAnswer
Oxidation Loss of electron by a molecule, atom or ion
Reductions Gain of electron by a molecule, atom or ion
Reducing agent Loses electrons and is oxidized
Oxidizing agent Gains electrons and is reduced
K + CL = K+ + CL- K= Oxidizing Agent
K + CL = K+ + CL- CL= Reducing agent
Catalyst Substance that accelerates the speed of a chemical reaction without itself being transformed or consumed by the reaction
Ionic bond Generally between non-metals and metals
Ionic bond Atom with a tendency to loose electrons and atom with tendence to gain electrons=chemical stability
Covalent bond two or more atoms share electrons to achieve chemical stabilitu
molecule tightly bonded groups of atoms
compund molecule that contains at least two different elements
solution mixture where one substance dissolves into another
static electricity imbalance of positive and negative charges
electric current movement of electrons that flow
series circuit electrons flow in a single path from source to destination: ex, battery hooked up to light bulb. Electricity flows from battery to lightbulb and continues in one direction, not reversed
Parallel circuit More than one path is provided for electrons to flow
Kinetic energy Energy of motion
Potential energy Stored energy
Electric energy Energy of moving electrons
Thermal energy Energy of heat
Radiant energy Energy of electromagnetic waves and light
Nuclear energy Stored energy of chemical nuclei
The cause of electricty Movement of electrons escaping from an atom
The cause of magnestism Spinning of electrons with still part of an atom
Electricity Chemicals may produce electricity
Electricity Magnetism may produce electricity
Electricity Heat and light may produce electricity
Ampere Unit used to express the number of electrons passing by a given point in a conductor
Voltage Force or pressure extered upon the electrons in the conductor
Resistance the opposition to the flow of current in the circuit
Ohm Measurement of resistance

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
