Question

Which of the following trends can be observed when moving down a column in the periodic table

Answer 1

Explanation:

A column on the periodic table represents a period.

These are some of the variations observed across a period;

• Atomic radii decreases progressively from left to right due to the progressive increase in the nuclear charge without an attendant increase in the number of electronic shells.
• Ionization energy increases progressively from left to right due to decreasing atomic radii.
• Electronegativity increases from left to right.
• Electropositivity decreases across a period.
