Periodic Table of Elements
The Periodic Table of Elements is a tabular display of the chemical elements, organized by their atomic number, electron configuration, and recurring chemical properties. Here is a breakdown of the elements based on their classification:

Metals
- Metals are elements that are typically solid at room temperature, shiny, malleable, and good conductors of heat and electricity. They make up the majority of the elements on the periodic table.
- Examples of metals include iron, gold, copper, and aluminum.

Non-metals
- Non-metals are elements that are generally poor conductors of heat and electricity, and often exist in the form of gases or brittle solids.
- Examples of non-metals include carbon, sulfur, oxygen, and nitrogen.

Metalloids
- Metalloids are elements that have properties intermediate between metals and non-metals. They are also known as semimetals.
- Examples of metalloids include silicon, arsenic, and germanium.

Key Components of the Periodic Table
- Name: The name of the element.
- Atomic Number: The number of protons in the nucleus of an atom of the element.
- Atomic Mass: The average mass of an atom of the element, taking into account the different isotopes.
- Classification: Whether the element is a metal, non-metal, or metalloid.
Understanding the periodic table and the classification of elements is essential in the field of chemistry, as it helps scientists predict the behavior and properties of different elements based on their placement in the table.
