The Periodic Table Review of Terms and Concepts Worksheet provides an in-depth exploration of the fundamental principles and concepts that underpin the organization and properties of elements within the periodic table. This comprehensive resource serves as an invaluable tool for students seeking to deepen their understanding of chemistry and its applications.
The worksheet encompasses a wide range of topics, including the definition and significance of the periodic table, the organization of elements based on atomic number and electron configuration, and the periodic trends in atomic radius, ionization energy, electron affinity, and electronegativity.
Periodic Table Review: Key Concepts
The periodic table is a tabular arrangement of chemical elements, organized on the basis of their atomic number, electron configuration, and recurring chemical properties. It is a powerful tool for understanding the chemical behavior of elements and predicting the properties of new elements that have not yet been discovered.
Organization of Elements in the Periodic Table
- Atomic Number:The number of protons in the nucleus of an atom.
- Atomic Mass:The weighted average mass of all the isotopes of an element.
- Electron Configuration:The distribution of electrons in the atomic orbitals.
Periodic Trends
- Atomic Radius:The distance from the nucleus to the outermost electron shell. Generally decreases across a period and increases down a group.
- Ionization Energy:The energy required to remove an electron from an atom. Generally increases across a period and decreases down a group.
- Electron Affinity:The energy change when an electron is added to an atom. Generally increases across a period and decreases down a group.
- Electronegativity:The ability of an atom to attract electrons. Generally increases across a period and decreases down a group.

Elements and their Properties
The periodic table can be used to organize elements based on their group and period. Elements in the same group have similar chemical properties, while elements in the same period have the same number of electron shells.
Table of Elements
Group | Period | Element |
---|---|---|
1 | 1 | Hydrogen |
2 | 1 | Helium |
13 | 3 | Aluminum |
17 | 3 | Chlorine |
18 | 3 | Argon |
Properties of Representative Elements
- s-block elements:Alkali metals (Group 1) and alkaline earth metals (Group 2).
- p-block elements:Main-group elements (Groups 13-18).
- d-block elements:Transition metals (Groups 3-12).
- f-block elements:Inner transition metals (Lanthanides and Actinides).
Periodic Trends and Patterns
The periodic table shows clear trends in the properties of elements. These trends can be used to predict the properties of unknown elements.
Observed Periodic Trends, The periodic table review of terms and concepts worksheet
- Atomic Radius:Decreases across a period and increases down a group.
- Ionization Energy:Increases across a period and decreases down a group.
- Electron Affinity:Increases across a period and decreases down a group.
- Electronegativity:Increases across a period and decreases down a group.
Exceptions to the Periodic Trends
- Atomic Radius:Helium has a smaller atomic radius than hydrogen.
- Ionization Energy:Boron has a higher ionization energy than beryllium.
