Study Notes
Periodic Classification and Atomic Number
- The significance of atomic number lies in its ability to uniquely identify an element and determine its position in the periodic table.
- Atomic number is the basis for periodic classification, as it is used to arrange elements in a logical and systematic order.
Electronic Configuration and Blocks
- Electronic configuration is the arrangement of electrons in an atom's energy levels or shells.
- Elements can be classified into s, p, d, and f blocks based on the orbital that is being filled with electrons.
- Main characteristics of each block:
- s-block: elements with one or two electrons in the outermost energy level, exhibiting highly reactive properties.
- p-block: elements with three or more electrons in the outermost energy level, exhibiting varying properties.
- d-block: elements with partially filled d-subshells, exhibiting catalytic and magnetic properties.
- f-block: elements with partially filled f-subshells, exhibiting strong magnetic and catalytic properties.
Periodic Trends and Properties
- Periodic trends refer to the gradual changes in physical and chemical properties of elements across a period or group.
- Elements exhibit periodic trends in properties such as:
- Atomic radius
- Electronegativity
- Ionization enthalpy
- Electropositivity
- These trends can be explained by the changes in electronic configuration and atomic number.
Ionization Enthalpy and Metallic Character
- Ionization enthalpy is the energy required to remove an electron from an atom.
- Metallic character increases as ionization enthalpy decreases, indicating a higher tendency to lose electrons.
IUPAC Nomenclature and Elements with Z > 100
- Elements with atomic number (Z) greater than 100 are named according to IUPAC nomenclature.
- Examples include:
- Ununennium (Uue, Z = 119)
- Unbinilium (Ubn, Z = 120)
Purpose and Law of the Periodic Table
- The main purpose of the periodic table is to organize and systematize elements based on their atomic number and properties.
- The periodic law states that the properties of elements recur periodically when elements are arranged in order of increasing atomic number.
Importance of Atomic Number
- Atomic number is a fundamental property of an element, determining its position in the periodic table.
- It is used to identify and distinguish elements from one another.
Atomic Properties and Scientific Vocabulary
- Examples of important properties of atoms that can be explained using scientific vocabulary include:
- Electron affinity
- Electronegativity
- Ionization energy
- Atomic radius
- Metallic character
