Things the kids have stolen from me
The total amount of energy in a closed system remains unchanged, although it can be converted from one form to another. What Law illustrates this?
the Law of Conservation of Energy
Anything that has mass and takes up space
Matter
The fundamental building block of matter is the atom, which is made up of which three things?
Protons, neutrons, and electrons.
An arrangement of the elements in order of increasing atomic number
Periodic Table
The splitting of a nucleus into at least two smaller nuclei with an accompanying release of energy
Fission
The ability to do work
Energy
What are the three states of matter?
Solid, Liquid, and Gas
The number of protons in the nucleus of an element
Atomic number
Which term collectively refers to the protons and neutrons found in the nucleus of an atom?
Nucleons
The condition in which the neutrons produced by fission are equal to the number of neutrons in the previous generation.
Criticality
A force acting through a distance
Work
Which state of matter has an indefinite shape, but definite volume?
Liquid
The number of protons plus neutrons of a particular isotope of an element.
Mass number
The energy equivalent of the mass defect, this is the energy that holds the nucleus of an atom together.
Binding Energy
The process of combining nuclei into a larger nucleus with an accompanying release of energy.
Fusion
Energy of motion
Kinetic energy
Which state of matter has an indefinite shape and volume?
Gas
The actual mass of an atom of a particular isotope (expressed in atomic mass units or AMU)
Atomic mass
A species of atom characterized by the constitution of its nucleus--by its number of protons and neutrons, and energy content.
Nuclide
If two or three neutrons produced in one fission each go on to produce another fission, the number of fissions and the production of neutrons increase exponentially, creating a chain reaction that is ____ ______.
Supercritical
Any action on an object that can cause the object to change speed or direction
Force
Which state of matter has a definite shape and volume?
Solid
Atomic Weight
Nuclides that have the same number of protons but different numbers of neutrons
Isotope
Pair (Production and) Annihilation is an example of what Law?
Law of Conservation of Energy
