Lecture Notes on Carbon and Atomic Structure

Overview of Carbon

  • Carbon is a highly versatile element, integral to many processes, particularly in living organisms.

Structure of an Atom

  • Every atom consists of three main subatomic particles:

    • Protons: Positively charged particles found in the nucleus.

    • Neutrons: Neutral particles also located in the nucleus.

    • Electrons: Negatively charged particles that orbit the nucleus.

Atomic Models

  • The Bore model is a traditional representation of an atom.

    • Depicts electrons moving in orbits around the nucleus.

Valence Electrons and Chemical Reactions

  • Only outermost electrons, known as valence electrons, are involved in forming molecules or compounds when atoms interact.

  • The interaction of these valence electrons dictates how atoms bond with each other to create various substances.

    • Valence shell: The outermost electron shell of an atom where bonding occurs.

  • Understanding valence electrons is crucial in predicting the behavior of atoms during chemical reactions and their ability to form different compounds.

Importance of Carbon's Versatility

  • Carbon's ability to form a wide variety of compounds is largely due to its four valence electrons, allowing it to form stable bonds with many elements.

  • This property is essential for the complexity of organic molecules, making carbon fundamental to life as we know it.
