Term
| Inverse relationship between frequency and wavelength |
|
Definition
| C(Speed of light) = Lambda(Wavelength)* V (nu: the frequency) |
|
|
Term
| Energy of a photon (packet) |
|
Definition
| Energy = h(planks constant) * h (frequency) |
|
|
Term
| De Broglie equation, used to relate wavelength of a particle to is mass and velocity |
|
Definition
| Lambda(wavelength) = h(planks constant) /(mass * velocity) |
|
|
Term
|
Definition
| The inner electrons partially shield the outer valance electrons from the pull of the protons. Protons - Non Valence electrons = Zeff |
|
|
Term
|
Definition
| Effective charge increase as we move across the rows of the periodic table. Zeff increase slightly as we go down the table. |
|
|
Term
|
Definition
| With in each column, atomic radius tends to increase from top to bottom because of increases of quantum number. Within each period the radius decreases from left to right because of Zeff. |
|
|
Term
|
Definition
| a group of ions all containing the same number of electrons. |
|
|
Term
|
Definition
Minimum energy required to remove an electron from the ground state. For example the first ionization energy is the energy needed to remove the first electron from a neutral atom.
Na-->Na+ + e- |
|
|
Term
| Trends in Ionization Energy |
|
Definition
| With each row of the table I1 increases with atomic number. The alkali show the lowest while noble gases show the highest. With each group the ionization energy generally decreases with increasing atomic number. |
|
|
Term
|
Definition
| Energy change that occurs when electron is added. The opposite of an ionization energy. |
