Equation for Wavelength
v=f*wavelength
Equation for Frequency
c=wavlength*v
Equation for Energy
E=h*v
h stands for
Planck’s contant (h= 6.626 x 10^-34)
What is the trend for atomic radii?
Atomic radius decreases as you move left to right across a period
What is the trend for ionization energy?
Decreases from top to bottom in groups and increases from left to right across a period
What is the trend for electronegativity?
Increases as you move from left to right across a period and decreases as you move down a group
Why does the trend for electronegativity occur?
As the number of protons in the nucleus increases, the electronegativity will increase
Why does the trend for ionization energy occur?
The increasing nuclear charge results in the outermost electron being more strongly bound to the nucleus
Why does the trend for atomic radii occur?
Increasing of charge as you move left to right across a period
Identity of an ion
an element that has a charge
How is light released from an atom?
When the electrons return to lower energy levels they will release extra energy and that can be in the form of light
How does different wavelengths and frequencies affect light?
Light toward the red end of the spectrum has longer wavelengths and lower energy than light toward the violet end of the spectrum
What are the different types of light?
Alpha, Beta, Gamma
Gamma is…
The highest level of light
Beta is…
Neutral level of light
Alpha is…
Lowest level of light
Aufbau principle
electrons fill the lowest level than work their way up
Hunds principle
orbitals of equal energy are each occupied by one electron before any orbital is occupied by a second electron
Pauli Exclusion prinicple
two electrons in the same atom can have identical values for all four of their quantum numbers
What is a principal energy level?
the shell or orbital in which the electron is located relative to the atom’s nucleus
What is a sublevel?
The energy levels that hold electrons
What are orbitals?
A region of space within an atom where an electron in a given subshell can be found
What is a atomic radii?
The measure from the nucleus to the outermost electrons
What is ionization energy?
The amount of force it takes to remove a electron
What is electronegativity?
The measurement of force that the nucleus has on a pair of shared electrons
