Study Notes
Electron Affinity and Ionization Energy
- The process associated with the addition of an electron to the element B is electron affinity.
Electronegativity
- Oxygen has a higher electronegativity than sulfur due to its smaller atomic size.
- Fluorine is the most electronegative element primarily because of its very small atomic size.
- Oxygen has a higher electronegativity than nitrogen due to its smaller atomic size.
Atomic Size
- As the number of electron shells in an element increases, the atomic size also increases.
- The trend for atomic size in the periodic table is that it generally decreases from left to right across a period and increases down a group.
Ionization Energy
- Ionization energy decreases when going down a group in the periodic table.
- The trend for ionization energies across a period is that they generally increase from left to right.
Atom Stability
- The definition of electron affinity is the energy change associated with the addition of an electron to a neutral atom.
- A stable atom is one that has a full outer energy level, while an unstable atom is one that does not have a full outer energy level.
