Question | Answer |
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 |
