Chapter 3: Quantum Theory and the Electronic Structure of Atoms Flashcards
What is energy?
The capacity to do work or transfer heat.
What is kinetic energy?
Energy that is associated with motion.
What is the equation for kinetic energy?
Ek= 1/2mu^2
What is potential energy?
Energy possessed by an object by virtue of its possession.
What is chemical energy?
Stored inside structural units of a chemical substance.
What is the electrostatic energy?
Potential energy that results from interaction of charged particles.
Whats the equation for electrostatic potential energy?
Eel=Q1Q2/d
Are kinetic energy and potential energy interchangeable?
YES
Whats significant about the Law of conservation?
Energy cannot be created or destroyed.
What is the unit of energy?
Joule (J)
1 J = 1 N X m
1 N = 1 kg X m/s^2
1 kJ = 1000 J
What is electromagnetic spectrum?
the range of wavelengths or frequencies over which electromagnetic radiation extends.
What is a wavelength?
(LAMBDA) Distance between identical points of successive waves
What is frequency?
(NU) The number of waves that pass through a particle point in one second.
What is amplitude?
The vertical distance from the middle of a wave to the top of the peak or bottom of trough.
Whats the equation for amplitude?
c = (lambda)(nu)
