Periodic Table
an arrangement of the elements by increasing atomic number
What is the periodic table
the ability to cause change or make things happen
What is a energy?
The temperature at which a substance changes from a solid to a liquid.
Who is melting point?
a disruption that carries energy from one place to another
What is a wave?
stored energy
What is a potential energy?
The amount of mass present in a given volume of a substance (one example of a characteristic property)
What is density?
a wave that needs matter to be present in order to transfer energy from place to place (for example sound)
What is a mechanical wave?
the type of energy that is build up by raising something high above ground
What is a gravitational potential energy?
Properties that can be tested without changing the chemical nature (identity) of a substance
What are physical properties?
the wave that does not need matter to be present in order to transfer energy (for example light)
What is an electromagnetic wave?
the type of energy stored in a bow an arrow as the shooter pulls back the bow
What is a elastic potential energy?
Properties that cannot be tested without risking changing the identity of a substance
What are chemical properties?
a model that lists all of the electromagnetic waves, usually in order by freqency/wavelength
What is the electromagnetic spectrum?
the electrons found on the outermost level of an atom; equal to the last digit in the group number
What is are valence electrons?
a quantity that increases kinetic and potential energy as it increases
What is mass?
Properties not affected by amount or shape of a substance and can be used to identify different types of matter
What are characteristic properties?
2 wave properties that increase as the energy a wave is carrying increases
What is frequency and amplitude?
an atom that has a positive or negative charge; an atom that is not neutral
What is an ion?
