Physics Unit 1 Flashcards
What are the 3 fundamental particles of the atom
Neutron, electron, and proton
What is the max # of electrons permitted in the N-shell
32
Which electron shell is located closest to the nucleus
K-shell
How many electrons can the L-shell hold
8
The number of protons in the atoms nucleus is reflected in its
Atomic #
The # of protons and neutrons in the atoms nucleus is the
Atomic mass #
T/F The kinetic energy of a body turns into potential energy when the body is put into motion
False
T/F Energy cannot be created or destroyed but diverted into other forms of energy is know as the theory of relativity
False
Actual or potential ability to do work
Energy
Anything that occupies space and has form
Matter
Force x distance
Work
Energy in motion
Kinetic energy
Stored energy
Potential energy
Simple substance that cannot be broken down
Element
Complex substance made of 2 or more elements that are chemically United
Compound
Smallest particle of an element that still possesses the chemical properties of that element
Atom
When 2 or more substances are combined
Mixture
Energy
Joule
Mass
Kilogram
Velocity
Speed of light
Wavelength
Angstrom
Hertz
Frequency
When atoms of one element change to atoms of another element because of the loss of a proton is know as
Radioactive decay
The process of adding or removing an electron from an atom is known as
Ionization
When an atom has the same # of protons but different # of neutrons it is known as
Isotope
Elements on the periodic table are listed by their
Atomic #
