Can you help me create a study plan for my Chemistry exams, focusing on Atomic Structure and Electronic Structure?

• Go through your CHM 101 and UTME Chemistry past questions.
• Find all questions related to:
  • Atomic models (Dalton, Thomson, Rutherford, Bohr)
  • Subatomic particles (protons, neutrons, electrons) and their properties
  • Atomic number, mass number, isotopes
  • Periodic trends (electronegativity, ionization energy, atomic radius)
  • Electron configuration (e.g., $1s^2 2s^2 2p^6$)
  • Quantum numbers (if covered in CHM 101)

• Now, open your Chemistry PDF notes.
• Go directly to the sections covering "Atomic Structure," "Periodic Table," and "Electronic Structure."
• Do not read everything. Focus on:
  • Definitions: What is an atom? What are isotopes? What is ionization energy?
  • Key Concepts: How do electrons fill orbitals? What are the rules (Aufbau, Hund's, Pauli exclusion)? How do periodic trends change across a period and down a group?
  • Examples: Look at examples of electron configurations for different elements. Understand how to determine the number of protons, neutrons, and electrons from atomic and mass numbers.

• Work through the past questions you identified in Step 1.
• Try to solve them without looking at your notes first.
• If you get stuck, refer back to the specific section in your PDF notes.

Let's begin with a specific concept from this topic.

Question:
What are the three main subatomic particles, and what are their relative charges and locations within an atom?
