Radio Waves
The shortest wavelength and most
energetic photons are those of?
Gamma Rays
What is the ground state?
Lowest energy state
What are the energy levels?
n=2
n=3
n=4
so on
Light is a form of what?
Electromagnetic Radiation
Light's properties are?
Waves and Particles
What does white light contain?
contains a spectrum of wavelengths and therefore a
the spectrum of color.
What do Noble gases have? And what do they not want to do?
they have a full cloud and full valance elections. Highly stable. they do not want to share or give away their valance electrons
Every orbital contains how many electrons?
2 electrons
Who was the three important scientists who played a role in the development of quantum mechanics?
Niels Bohr, Erwin Schrödinger, along with
Albert Einstein.
Light is a type of energy that travels at a constant speed of? (not visible)
a constant speed of 3.0 × 108 m/s
(186,000 mi/s).
On the electromagnetic spectrum, visible light is a small portion. With visible light what has the longest wavelength and the shortest wavelength?
Longest- Red
Shortest- violet
The way elements are reactive is due to what?
Electrons, and electrons in the electron cloud.
Orbitals within the s subshell have a what shape?
Spherical shape
What are the two important models we examine?
Bohr model and Quantium Mechanical model
What is the definition of the wavelength of light?
defined as the distance between adjacent
wave crests.
High frequency = ________ energy
High
If an electron moves from n=3 to n=5 is it absorbing or losing energy (emitting visible light)?
it is absorbing energy.
When an element absorbs energy it gets?
Excited=excitation
What do the two models we focus on explain?
How electrons exist in atoms and how those electrons affect the
chemical and physical properties of
elements.
What is the definition of frequency in the terms of light?
is defined as the number of cycles or crests that pass through a stationary point in one second.
High Energy = _________ wavelength
Short, smaller
What is the Principal quantum number?
The energy levels.
When an element relaxes back to lower energy it is?
Relaxcation
