Page 1: Atomic Structure Fundamentals

This page introduces the fundamental concepts of atomic structure, focusing on subatomic particles and their arrangement. The content explores electron shells and energy levels within atoms.

Definition: Atoms are the basic building blocks of matter, composed of protons, neutrons, and electrons.

Highlight: Electrons occupy shells based on energy levels, with outer shells having higher energy than inner shells.

Vocabulary:

  • Nucleus: Central core containing protons and neutrons
  • Electron shells: Energy levels where electrons orbit
  • Electrostatic attraction: Force between oppositely charged particles

View

Page 2: The Periodic Table

This page details the organization of the periodic table and introduces the first 20 elements. It explains atomic numbers and mass numbers, providing essential information for understanding element classification.

Example: Aluminum (Al) has an atomic number of 13 and a mass number of 27.

Definition: The atomic number represents the number of protons in an atom's nucleus, while the mass number is the total of protons and neutrons.

Highlight: The periodic table contains 118 elements arranged by increasing atomic number.
