Trends in the periodic table

Question	Answer
Trends in ionisation energy	down going down a group due to increase in the screening effect and atomic radius
Trends in ionisation energy	increases across a period, due to increased nuclear charge and decrease in atomic radius
Trends in reactivity	Increases down a group, due to lower ionisation energy,and lower electronegativity
Trends in reactivity	decreases across a period, due to reduction in ionisation energy and atomic radius
Trends in electronegativity	decreases down a group due to the increasing atomic radius and the screening effect
Trends in electronegativity	Increases across a period due to an increase in nuclear charge and a decrease in atomic radius
Trends in atomic radius	increase down a group due to the increase in the number of shells/energy levels
Trends in atomic radius	Decrease across a period due to the increase in nuclear charge drawing shells closer to the nucleus
Trends in metallic character	increase up and across the periodic table
