Competency- Electromagnetic Radiation Flashcards
P orbitals are shaped like what?
A peanut
A spherical electron cloud surrounding an atomic nucleus would best represent what?
An S orbital
A 3D region around a nucleus where an electron may be found is called…
An orbital
What is electromagnetic radiation?
It’s energy that can travel through space with both wave-like and particle-like properties
Definition of amplitude
The maximum extent of a wave
What happens when an atom is given more energy?
It moves further in relation to the nucleus of an atom and the further away it is from the nucleus
Where does electromagnetic radiation come from?
When an atom absorbs energy, the electrons jump to a higher energy level, but can’t stay at this higher level forever. When the electron falls back to its ground state, a photon of electromagnetic radiation is emitted
Define valance electrons
Valance electrons are the furthest electrons from an atom.
What is Heisenberg uncertainty principal
?
We can only know a probability of where an electron might be. Instead, the are most likely in orbitals, we just don’t know where they are in the orbital.
