Untitled Deck Flashcards
What is electromagnetic radiation?
A form of energy that exhibits wavelike behavior through space.
What is the electromagnetic spectrum?
All forms of electromagnetic radiation.
What is wavelength?
The distance between corresponding points on adjacent waves.
What is frequency?
The number of waves that pass a given point in a specific time, usually one second.
What is the photoelectric effect?
Refers to the emission of electrons from a metal when light shines on the metal.
What is a quantum?
The minimal quantity of energy that can be lost or gained by an atom.
What is a photon?
A particle of electromagnetic radiation having zero mass and carrying a quantum of energy.
What is the ground state?
The lowest energy state.
What is the excited state?
The highest energy state.
What is a line emission spectrum?
They put a pinkish light they got from a vacuum through a prism and it separated into four colors. It’s the four bands of light.
What is Bohr’s Model?
The electron can circle the nucleus only in orbits.
What is the Heisenberg uncertainty principle?
It states that it’s impossible to determine simultaneously both the position and velocity of an electron or any particle.
What is quantum theory?
Describes the wave properties of electrons.
What is the principle quantum number?
The main energy level occupied by the electron.
What is an orbital?
A 3D region around the nucleus that indicates the possible location of an electron.
