Study Notes

Periodic Law

  • The Periodic Law states that the properties of elements are periodic functions of their atomic numbers, revealing trends in elemental properties as atomic number increases.

Classification of Elements

  • Elements are classified based on their chemical properties, which helps in understanding similarities and differences among different groups of elements.

Electronic Configuration Classification

  • Elements can also be classified based on their electronic configuration, which describes the distribution of electrons in an atom's orbitals.

Ionization Energy

  • Ionization energy refers to the energy required to remove an electron from an atom or ion, indicating how easily an atom can lose an electron in chemical reactions.

Types of Chemical Bonds

  • The three types of chemical bonds include ionic bonds, covalent bonds, and metallic bonds, each defined by how atoms interact and share or transfer electrons.
