What are Periodic Properties? Explain with Examples.
Answer (1)
Periodic properties are properties of elements that show a regular pattern (trend) across periods and down groups in the periodic table.
Examples:
-
Atomic radius: decreases across a period, increases down a group.
-
Ionization enthalpy: increases across a period, decreases down a group.
-
Electron gain enthalpy: becomes more negative across a period (till group 17).
-
Electronegativity: increases across a period, decreases down a group.
-
Valency: shows a definite trend based on group number.
