What does the Quantum Mechanical Model suggest about electrons?
Electrons move in fixed orbits around the nucleus
Electrons can be found anywhere in orbitals around the nucleus
Electrons do not interact with light
Electrons are stationary within the atom
Which scientist is credited with the development of the orbitals in the Quantum Mechanical Model?
Bohr
Schrodinger
Heisenberg
Rutherford
In Quantum Mechanics, the denser the electron cloud,
the more likely the electron is to be found there
the less likely the electron is to be found there
the more likely the electron is to have a positive spin
the less likely the electron is to have a positive spin
Quantum Mechanics says that electrons
can act as both a particle and a wave
can neither act as both a particle and a wave
are a pure form of a wave only
are particles only
True or False:
According to quantum mechanics, we can't exactly tell where an electron is located, we can only predict where it's usually found the most
True
False
