This is a draft cheat sheet. It is a work in progress and is not finished yet.
Electronegativity
Increases Across the Table |
- The Atomic number increases |
- The number of protons increases |
- The valence electrons all go in the same shell |
- The nuclear charge is effective |
- The attraction between the protons and electrons increases |
= Therefore the electronegativivity increases |
Electronegativity
Decreases Down the Table |
- The number of shells increases |
- The electrons are further away from the nucleus |
- The amount of shielding increases |
- The attraction between the protons and electrons decreases |
= Therefore the electronegatitvity decreases |
|

Atomic Radii
Increases Down the Table |
- Number of protons increase |
- The positive charge of the nucleus increases |
- The number of shells increase |
- Shielding is increased |
- The attraction between electrons and protons decrease |
= Therefore the atomic radii increases |
Atomic Radii
Increases Down the Table |
- The Atomic number increases |
- The number of protons increases |
- The positive charge of the nucleus increases |
- Valence electrons are added to the same shell |
- The protons and electrons are attracted |
- The valence shell is pulled towards the nucleus |
= The atoms are smaller |
