Flashcards in RT 205 HW1 Deck (44):
Smallest part a substance and still retain the properties of that substance
The small dense center of an atom, which contain nucleons (neutrons and protons)
Radius of an atomic nucleus
Radius of an atom
Equal to the number of protons and neutrons in an atom
Equal to the number of protons in an atom, and also equal to the number of electrons in a stable atom.
# AMU in proton
# AMU in neutron
# AMU in electron
Proton: Weight in Kg
Neutron: Weight in Kg
Electron: Weight in Kg
When Z=differerent, N=Same
When N=different, Z=Same

1 AMU = ___________ MeV
The mass of a single atom
The amount by which the mass of an atomic nucleus is less than the sum of the masses of its constituent particles.
The energy required to separate a single particle or group of particles from a molecule, atom, or nucleus.
The emission or transfer of radiant energy as particles, electromagnetic waves
A stream of atomic or subatomic particles that may be charged positively or negatively or not at all.
Any of the atomic particles that compose matter and energy, such as protons, neutrons, and electrons
Velocity= Frequency x Wavelength
High frequency, high energy EM radiation interacts like a particle when contracting matter. Photon energy and frequency are directly related.
The spontaneous emmission of radiation, either directly from unstable nuclei, or as a consequence of a nuclear reaction

Define Force and give derived and SI Units
Anything that changes an objects's motion
F= mass x acceleration
= Kg m/s^2
Define Work and give derived and SI Units
Measures the change a force has on an object's position or motion
W= Force x distance
= N x m
= kg m/s^2 x m
Define Power and give derived and SI Units
Rate at which work is done
P= Weight / time
= Kg m^2/s^2/s
= Kg m^2/s^3
= Watt (W)
Define Energy and give derived and SI units
The ability to do work
Derived = E , SI= J

A substance that cannot be split into simpler substances
The type of valence when an atom donates an electron
The type of valence when an atom gives or accepts an electron
The giving and accepting of electrons between atoms
Atoms that share the outermost shell
Non-Polar Covalent Bonds
Atoms alignment creates a positive charge at one end and a negative charge on the opposite end.
Polar Covalent Bonds
Attraction/ repulsion stability that forms between two atoms when they share electrons
