Periodic Table Trends Worksheet Answer Key Pdf

Worksheet 11 – Periodic Trends A number of physical and chemical properties of elements can be predicted from their position in the Periodic Table.Among these properties are Ionization Energy, Electron Affinity and Atomic/ Ionic Radii. These properties all involve the outer shell (valence) electrons as well as the inner shell (shielding) electrons. …

Periodic Trends Worksheet – Solutions 1) Rank the following elements by increasing atomic radius: carbon, aluminum, oxygen, potassium. From smallest to largest: oxygen < carbon < aluminum < potassium 2) Rank the following elements by increasing electronegativity: sulfur, oxygen, neon, aluminu m. From smallest to largest:

Answers to Comparing Ionization Energies Here are answers to the exercises above. a. Mg, Si, S All are in the same period and use the same number of energy levels. Mg has the lowest I.E. because it has the lowest effective nuclear charge. S has the highest I.E. because it has the highest effective nuclear charge. b. Mg, Ca, Ba

Atom Size decreases as we move Across ‣ Atomic Radius decreases as we move across the periodic table because the nuclear charge increases with each new row. ‣ Shielding within a period is minimal. ‣ Electrons have a minimal repulsion within a shell because they are in separate orbitals. ‣ They fit together well.
