Chemical elements are pure substances consisting of only one type of atom distinguished by their atomic number, which is the number of protons in their nuclei. The periodic table organizes these elements based on shared properties, helping scientists predict behavior and compounds.
Metals are a significant category of these elements:
- Silver (\( \mathrm{Ag} \)) is known for its conductivity and is used in electronics and currency.
- Magnesium (\( \mathrm{Mg} \)) is important in the human body and is utilized in construction for its strength and light weight.
Each element, whether metal, nonmetal, or metalloid, has unique characteristics and contributes to the complexity and diversity of materials and compounds found in nature and human-made products.
