ChemistryClassification of Elements and Periodicity in PropertiesJEE Main

Some periodic properties are given below. The number of properties that show a decrease in the general periodic trend down a group is . 1. Atomic radius 2. Ionic radius 3. Ionization enthalpy 4. Electron gain enthalpy 5. Electronegativity 6. Metallic character 7. Nonmetallic character 8. Valency

Answer: 4

Solution

Down a group: atomic radius increases, ionic radius increases, ionization enthalpy decreases, electron gain enthalpy (magnitude) generally decreases, electronegativity
