Unit 2 Experience 2 - The Periodic Table & Atomic Structure

Front

Why are Group 1 elements more reactive than Group 18 elements?

Back

Group 1 elements only have 1 valence electron making them mostly unstable and more reactive.

Front

The force between two charged particles.

Back

Coulombic Force

Front

Coulomb's Law

Back

The strength of the force between two charged particles depends on the charge of each particle and the distance between them.

Front

For two oppositely charged particles, a larger charge produces a ____ ____

Back

Stronger Attraction

Front

For two negatively charged (same charge) particles, a larger charge produces a ____ ____

Back

Stronger Repulsion

Front

Valence electrons do not receive the full attractive force of the nuclear charge (from the positively charged protons) because the core electrons shield some of it from the valence electrons.

Back

Shielding Effect

Front

Back

The net positive nuclear charge experienced by an electron in an atom.

Front

Effective nuclear charge ____ left to right and we can estimate the effective nuclear charge using the number of ____ ____.

Back

increases

valence electrons

Front

Back

Yes because they have the same number of valence electrons.
