Study Notes
Periodic Table of Elements
- The periodic table organizes elements based on their atomic structure and properties.
- Elements are arranged in increasing atomic number.
- Elements in the same column (group) share similar chemical properties.
- Elements in the same row (period) have increasing numbers of electron shells.
Element Properties
- Group Numbers: Correspond to the number of valence electrons.
- Valence Electron Numbers: Indicate how many electrons an atom can gain or lose to form chemical bonds; listed in light blue or gray under the element in the table.
- Examples: Carbon (C) has valence electrons 2, 4; Oxygen (O) has 2, 6; Nitrogen (N) has 1, 3, 5; Silicon (Si) has 2, 4; Fluorine (F) has 1; Sodium (Na) has 1; Magnesium (Mg) has 2.
Element Names and Symbols
- Elements are represented by a one- or two-letter symbol (e.g., H for Hydrogen, O for Oxygen).
- The name of the element is also given next to the symbol; some in Spanish and some in English.
