Periodic Table Trends

The energy change that occurs when an electron is added to a neutral atom.

The amount of energy required to remove an electron from a neutral atom.

Electronegativity increases from left to right across a period and decreases down a group.

Phosphorus has lower ionization energy than Nitrogen.

Lithium has smaller atomic radii than Sodium.

Atomic radii decrease from left to right across a period and increase down a group.

The tendency of an atom to attract electrons in a chemical bond.

As atomic radii increase, ionization energy generally decreases.

The properties of elements are periodic functions of their atomic numbers.

Elements in the same group have similar reactivity due to their similar valence electron configurations.
