Periodic Table Trends and similarities

Atomic Radius ½ the distance between the nuclei of two identical atoms that are bonded together. 1. electron – electron repulsion = makes atom larger 2. proton – electron attraction = makes atom smaller 3. p + to e - attraction 1 million times stronger than e - to e - repulsion

Electron Affinity The energy change that occurs when a neutral atom acquires an electron. This electron affinity value is negative.

Ionization Energy: The energy required to remove one electron from a neutral atom.

Electronegativity A measurement of the ability of an atom in a chemical compound to attract electrons.

Generally, Ionization energy + Electron Affinity = Electronegativity Ionization energy + Electron Affinity = Electronegativity Most electronegative element – Fluorine (F) Most electronegative element – Fluorine (F) It is assigned the number 4 It is assigned the number 4 All other values are based on this value. All other values are based on this value.

Density Mass of a material ____________________________ Volume of that material

Ionic Radius ½ the distance between the nuclei of two identical ions that are bonded together. Decreasing the number of electrons shrinks the ion size Isoelectric: two elements having the same electron configuration Increasing the number of electrons expands the ion size initially (see chart)

Periodic Trends Try to determine the trends by looking at the handouts provided.
