General Chemistry Formulas Chapter 1 Flashcards
What is the energy of a quantum formula?
E=hf
In the energy of a quantum formula what does h stand for?
It is a proportionality constant known as Planck’s constant.
Planck’s constant stands for what numerical value?
6.626 X 10^-34 Jxs?
What is the speed of light?
c=3.0 x 10^8 m/s
Give a formula that can calculate the speed of light or any wave?
v=f(lambda sign)
Formula for angular momentum of an electron.
L=nh/2(pi)
Formula for energy of an electron.
-RH/n^2
The energy of an electron increase or decrease the further it is away from an electron.
The energy of an electron increases
What does the Heisenberg uncertainty principle state?
That it is impossible to know both an electrons position and its momentum exactly at the same time
What is the symbol for the principal quantum number and what does it describe.
n; The average energy of the shell
What is the azimuthal quantum number symbol and what does it describe?
l; and it describe the subshells within a given principal energy level s, p, d, and f
What is the magnetic quantum number symbol and what does it specify?
ml; The particular orbital within a subshell where an electron is likely to be found at a given moment in time
What is the spin quantum number symbol and what does it indicate?
ms; indicates the spin orientations +or- 1/2 of an electron in an orbital
Hund’s rule.
State that subshells with multiple orbitals fill electrons so that every orbital in a subshell gets one electron before nay of them gets a second.
Parameagnetic
materials with unpaired electrons that align with magnetic fields, attracting the material to a magnet.
