The Atomic Model
Radiation
Nuclear Fission
100
This model shows how a system works and predicts its behavior
What is the conceptual model?
100
Protons and neutrons are collectively called this.
What are nucleons?
100
These are the outermost electrons on each atom.
What are valance electrons?
100
The source of most radiation.
What are natural sources?
100
The difference between Nuclear Fission and Nuclear Fusion.
What is Fusion combines two nuclei, Fission breaks one into two?
200
The equation that predicts the angle of deflection.
What is angle of deflection= charge/mass?
200
The number of protons and neutrons make up this.
What is the mass number.
200
This is the effect of inner electrons partially blocking the nucleuses positive charge from the outer electrons.
What is inner-shell shielding?
200
The combination of two protons and two neutrons.
What is an alpha particle?
200
Usually the dominate force which holds all the nucleons together.
What is the strong nuclear force?
300
Name the partials the nucleus is made up of.
What are protons and neutrons?
300
These are known as the "cement" of the atom.
What are neutrons?
300
The outer shell experiences a diminished nuclear charge called this.
What is the effective nuclear charge?
300
A beta particle is this.
What is an electron ejected from a radioactive nucleus?
300
Most energy released during nuclear fission is kinetic energy yet a much smaller amount that is released as this.
What is gamma radiation?
400
A modern name for the cathode ray particle.
What is an the electron?
400
Different isotopes have different mass numbers but the same charge this is because only one thing is different about them.
What are neutrons?
400
This is the amount of energy needed to pull an electron away from an atom.
What is ionization energy?
400
The changing of one element to another.
What is transmutation?
400
Energy is released in both fusion and fission. True or False
True
500
Explain what the gold foil experiment is and what is discovered.
What is a experiment by Rutherford that discovered the atomic nucleus by directing alpha particles through a gold sheet?
500
This is symbolism
What is a way of showing elements mass number and atomic number other than the periodic table?
500
Atoms don't pass through other atoms because of this.
What is the repulsion forces between electrons?
500
About 20% of the radiation we are exposed to comes from this.
What are medical procedures?
500
This is a chain reaction.
What is a self-sustaining reaction in which the products of one reaction can initiate further reaction events?
