what charges does a proton, neutron, and electron have
Positive, neutral, negative
define and isotope
an element with different a different number of neutrons
what would happen if your protons were to change in an atom
it would be a new element
define and ion
an element that had gained or lost electrons
how can you tell an atom has a negative charge, did it lose or gain electrons?
gained, it has more electrons than protons
how can you tell an atom has a positive charge, did it lose or gain electrons
lost, it has more protons than electrons

miles, au’s, light year, parsecs

photon
anything that has mass and takes up space
matter
a range of light energy based on wavelength, energy, and frequency
EM spectrum
Energy of light in different forms, some harmful some harmless
radiation
longest wavelength and lowest energy
radio

what type of energy is viewed with a spectroscope
visible light
energy that has the least amount of waves traveling in a certain amount of time
radio
type of energy that has the shortest wavelength measurement
gamma
what type of radiation are used to study the universe
all of them
instrument used for observing the wavelengths of visible light
spectroscope
theory of how the universe was formed
big bang
