Nuclear Decay/Fission/Fusion
What are the 3 types of Nuclear decay
ALPHA, BETA, GAMMA
What is the part of the Atom that changes in a nuclear reaction
The Nucleus
True or False, Equilibrium means a system is balanced
True
This term describes how fast a chemical reaction happens
Reaction Rate
An unstable atomic nucleus loses energy by emitting radiation
Real-life example of nuclear chemistry
After 2 half lifes of 100 grams of Iodine how much would remain
25 grams of Iodine
The Neutral particles found in the nucleus
Neutrons
What are the 2 types of Equilibrium
Static and Dynamic
Increasing this usually makes reactions happen faster (measured in degrees)
Temperature
The sun emits heat on the Earth. What example of chemistry is this
Real-life example of nuclear reactions
This type of decay includes a 3 as the mass # and a 2 as the atomic #
Alpha Decay
The amount of time it takes for half of the radioactive atoms in a sample to decay is known as the term
Half Life
The phrase “If a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change to re-establish an equilibrium" Refers to which Principle
Le Chatelier’s Principle
This factor involves how crowded reactant particles are, increased by adding more of a substance to speed up the reaction.
Concentration
The gravity pulls down on the book while the desk pushes up with the same force. What example of chemistry is this
Real-life example of Equilibrium
What type of particle is often used to initiate a Fission reaction
Neutron
What is radioactive decay
A natural process where an unstable nucleus sheds excess energy or particles to reach a more stable state.
If the concentration of a reactant is increased, the balance would shift
To the right
This substance speeds up a chemical reaction
Catalyst
A car rusting over time
Real-life example of reaction rates
A series of fission reactions is known as this
Chain Reaction
This type of radiation is pure electromagnetic energy It has no mass or charge
Gamma Radiation
What is Le Chatelier’s Principle
if you alter the conditions of a system in equilibrium (like concentration or pressure), the system will naturally shift to counteract that change and re-establish balance
Particles must collide with enough of this type of energy for a reaction to occur.
Activation energy
