  Understanding the organization of elements
• What is the focus of the topic "Metals and non-metals"?

  Understanding the properties and differences between metals and non-metals
• What is the focus of the topic "Groups 0, 1 and 7"?

  Understanding the properties of elements in these groups
• What are the key concepts in the topic "Atoms, elements, compounds"?

  • Atoms are the basic building blocks of matter
  • Elements are substances made of only one type of atom
  • Compounds are substances made of two or more different types of atoms chemically bonded together
• What are the key concepts in the topic "Atomic structure"?

  • Atoms consist of a nucleus (protons and neutrons) and electrons
  • Protons have a positive charge, neutrons are neutral, electrons have a negative charge
  • The number of protons determines the element
• What are the key concepts in the topic "History of the atom"?

  • Development of atomic theory from Dalton to modern quantum mechanics
  • Key contributions from scientists like Thomson, Rutherford, and Bohr
  • Evolution of the model of the atom over time
• What are the key concepts in the topic "Periodic table"?

  • Elements are arranged by increasing atomic number
  • Periods (rows) and groups (columns) have specific trends
  • Periodic trends include atomic radius, ionization energy, and electronegativity
• Formation of Ions


  Ions are formed when atoms gain or lose electrons to achieve a full outer energy level (octet). Cations form when atoms lose electrons, and anions form when atoms gain electrons.
