Study Notes
Elements and the Periodic Table
- Elements are substances that cannot be broken down into simpler substances.
- Examples include gold, which remains gold even when broken into smaller pieces.
- Over 100 elements are known.
- Each element has a unique name, symbol (shorthand), and atomic number.
- Atomic number orders elements across the periodic table.
- Element blocks provide atomic number, symbol, name, and atomic mass.
- Carbon (C) has the atomic number 6 and atomic mass 12.0107.
Periodic Table Structure
- The periodic table is organized into groups (vertical columns) and periods (horizontal rows).
- Each group and period defines a specific location for an element.
- Group numbers range from 1 to 18, and period numbers are 1 to 7.
- Example: Boron (B) is located in group 13, period 2.
Element Properties and the Periodic Table
- Elements within the same group share similar characteristics.
- The periodic table aids in identifying if an element is a metal, nonmetal, or metalloid.
- A staircase line separates metals (left side, excluding hydrogen) and nonmetals (right side).
- Metalloids are located along the staircase.
