Data Analysis & Models
This variable is found on the left column of a data table.
What is the independent variable?
As the wavelength increases, the frequency _________.
What is decreases?
_______________ is a particle of light with a specific amount of energy
What is a photon?
The _______________ is the center of an atom.
What is nucleus?
This feature on the periodic table identifies the number of protons in an atom of an element.
What is the atomic number?
This variable is on the Y-axis of a graph.
What is the dependent variable?
This color of light has the highest frequency.
What is violet?
A ____________ spectrum is a range of light with all wavelengths present, appearing as a continuous band of colors, like a rainbow. It is produced by hot, dense light sources.
What is continuous?
These subatomic particles have a positive charge
What are protons?
This feature on the periodic table can be used to determine the number of neutrons in an atom of an element.
What is the atomic mass (atomic weight)?
This variable is the variable that is changed, suspected cause.
What is the independent variable?
This EM radiation has the longest wavelengths.
What is radio waves?
An ______________________spectrum is the pattern of discrete colors (or wavelengths) of light produced when electrons in an atom or molecule drop from a higher energy state to a lower one, emitting a photon of energy.
What is emission?
These subatomic particles have a negative charge.
What are electrons?
Neutral atoms will have the same number of _____________ as protons.
What is electrons?
This variable os affected by the change; the effect.
What is the dependent variable?
Our eyes only see this type of EM radiation.
What is visible light?
An _____________________ spectrum shows dark lines against a continuous background where specific wavelengths of light have been absorbed by a material, revealing its unique atomic or molecular composition
What is absorption?
This tells us how many protons are in an atom.
What is atomic number?
This feature on the periodic table tells is the number of energy levels electrons can occupy in an atom,
What is the row number?
The italicized portion of the statement represents this variable.
If exposure to sunlight increases, then plants will grow taller.
What is the dependent variable?
Of all the visible light frequencies, red has the ___________ wavelengths.
What is longest?
Electrons achieve a higher energy state when they ___________ the right wavelength/frequency of EM radiation.
What is absorb?
To determine the number of neutrons in an atom, subtract the number of protons from the ____________.
What is atomic mass/weight?
