Quantum Mechanical Theory Flashcards
What is Quantum Mechanical Theory in relation to Bohr Theory and what is the concept of quantum electron configurement?
What is the Bohr theory?
An electron is a particle in orbit around a nucleus.
What is Quantum Mechanical Theory?
An electron is part of a cloud of negative energy surrounding a nucleus.
What is an orbital?
An area in 3D space where electrons are likely to be found.
The _______ an electron is to its nucleus, the higher its energy.
The closer an electron is to its nucleus, the higher its energy.
What is the shape of an s orbital?
Spherical.
True or False: An electron is both a particle and a wave.
True
What is the shape of a p orbital?
A pair of lobes, like a peanut or a dumbbell, on either side of the nucleus.
What are the four orbitals?
S, P, D and F
What is the main difference between the Quantum Mechanical and Bohr theory?
One is 3D and the other is 2D.
Loss of electrons is called:
Oxidation
Gain of electrons is called:
Reduction
When electrons are on the right side of an equation (they are gained), it is:
Oxidation
When electrons are on the left side of an equation (they are lost), it is:
Reduction
Metals are willing to ___________ electrons.
Lose/give up electrons.
Non-metals want to __________ electrons.
Take/gain electrons.
