Class 11ChemistryClassification of Elements and Periodicity in PropertiesMix Examples - Classification of Elements and Periodicity in Properties
MediumRepresent different types of periodic properties in the periodic table.
(N/A) The trends in periodic properties are as follows:
$1$. Across a period (left to right):
- Atomic radius decreases.
- Ionization enthalpy,electron gain enthalpy,and electronegativity generally increase.
- Non-metallic character increases,while metallic character decreases.
$2$. Down a group (top to bottom):
- Atomic radius increases.
- Ionization enthalpy,electron gain enthalpy,and electronegativity generally decrease.
- Metallic character increases,while non-metallic character decreases.
