ER&E Flashcards
Can you ever know where electrons are located?
No, according to the Heisenberg Uncertainty Principal, we can only know a probability of where the electron might be. We can’t know for certain. Instead, they are highly likely in orbitals, we just don’t know where they are in the orbital.
Wher does electromagnetic radiation ,which includes visible light, come from?
When an atom absorbs energy, the electrons jump to a higher energy level, but can’t stay at the higher level forever. When the electron falls back to its ground state, a photon of electromagnetic radiation is emitted.
The drop of an electron from high energy level to the ground state in hydrogen atom would be most closely associated with ______.
High- frequency radiation

What is electromagnetic radiation?
Energy that can travel through space with both wave like and particle like properties
A spherical electron cloud surrounding an atomic nucleus would best represent _______?
An s orbital
Unlike an orbit, in an orbital ________
An electron’s position cannot be known precisely of position
A three- dimensional region around a nucleus where an electron may be found is called ?
An orbital
