Elements and Periodic Table
- Metals are typically shiny, malleable, and good conductors of electricity.
- There are two liquid elements in the Periodic Table: Mercury (Hg) and Bromine (Br).
- Non-metals are typically dull, brittle, and poor conductors of electricity.
- Carbon is the only non-metal that is a good conductor of heat and electricity.
- A compound is a substance that contains two or more elements chemically bonded together.
- There are approximately 118 elements in the Periodic Table.
- The Periodic Table is organized by rows (periods) and columns (groups) based on the elements' atomic numbers and properties.
- The noble gases are a group of elements that are unreactive and include Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn).
