METALS AND NON-METALS
- The periodic table contains 118 elements, each unique in its chemical properties.
- Elements are categorized into three main groups: metals, nonmetals, and metalloids.
- They are typically hard, shiny materials with good thermal and electrical conductivity.
- Metals are also known for their unique malleable, ductile, and reflective properties
- metals are primarily located on the left side and in the middle of the periodic table
- The metals are lithium, sodium, potassium, calcium, iron, copper, silver, gold, and most elements in groups 1-12, excluding hydrogen.
- The nonmetal elements or nonmetals are a group of elements located on the right side of the periodic table except for hydrogen
- Nonmetals are natural elements used in pure form
- They are often brittle and poor conductors of heat and electricity
- Hydrogen, Helium, Carbon, Nitrogen, Oxygen, Fluorine, Neon, Phosphorous, Sulphur, Chlorine, and Argon are some of the examples
