-
What is the mass of a neutron?
It is (0.14%) heavier than the proton.
-
What is the particle called when a proton is broken down into a smaller particle?
It is called a(n) antineutrino.
-
What is a model?
It is a schematic description of a system that accounts for its known properties.
-
What is a Bohr Model?
It is a type of model that describes on what a(n) atom may look like, such as if I had a Bohr Model of helium, it would have 2 protons, 2 neutrons, and 2 electrons, He.
-
What is the nucleus of an atom?
It is the center of an atom, containing the protons and neutrons.
-
What is the speculative correct model for an atom named?
It is called the quantum-mechanical-model.
-
What is a(n) atomic number?
The number of protons in an atom.
-
What is the mass number on the periodic table?
It is the sum of the numbers of neutrons and protons in the nucleus of an atom.
-
What are Isotopes?
Atoms with the same number of protons, but with different numbers of neutrons.
-
What is a(n) element?
A collection of atoms that all have the same number of protons.
-
What is the Periodic Table of Elements?
It is a chart of where all the different element around the world are stored, it includes the atomic number, and the atomic mass for each element recorded on it.
-
What are Bohr orbits?
It is the orbit in which the electrons pass around the atom.
-
What are Yukawa called?
Pions.
-
What is a radioactive isotope?
An atom with a nucleus that is not stable.
-
What is half-life.
The time it takes for half of the original sample of a radioactive isotope to decay.
-
How do you determine what kind of atom you have?
You look at its atomic number.
