Chapter 5- Electrons
what I know about electrons
1- charge
Opposite charge of protons
Electrons are moving
the 1st orbital has 2 electrons
Neutral protons=electrons
They are found outside of the Nucleus
Electrons are small
1840 electrons= 1 protons mass
Today's model of Electrons: Cloud Model
Orbital Model: Bohr
Electron "orbits" the nucleus in specific
path like the planets orbit the sun
Light Energy
light energy gives off in waves
light particles are called protons
Series of Waves
Low frequency/Big wavelength- Radio Wave
Visible light (SPECTRUM)
Low energy ROY G BIP
High frequency/small wavelength- Gamma Ray
Energy Added - Excited State
Atomic Emission Specta
When atoms absorb energy, electrons move into higher energy levels. They will then lose energy and emit light when they return to lower energy levels.
Electrons just from high to low state
The bigger the jump, the more light is emitted.
Light emitted as electron jumps
The Principles and rules
Heisemberg's Uncertainty Principle
It is impossible to know the location and velocity of an electron at the same time.
Hund's Rule
Electrons spin the opposite direction in an orbital.
Paul's Exclusion Principles
1 or 2 electrons per orbital
Aufbau Principle
Electrons occupy the lowest energy level first
bucket filling with water. BOTTOM TO TOP
Ground State
Electron is the lowest possible energy level
Quantum Mechanical Model
Tells how likely it is to find an electron in various locations around the nucleus
A model of a Solar system resembles the Bohr model of an Nucleus in an atom
