Study Notes
Elements and Periodic Table
- 109 elements have been discovered, and any future discoveries will be beyond 109.
- The modern periodic table was devised by Mendeleev.
- The periodic table is arranged in seven horizontal rows (periods) and eighteen vertical columns (groups).
Periods and Groups
- Periods are horizontal rows in the periodic table, and groups are vertical columns.
- Elements in the same group have similar properties.
Lanthanides and Actinides
- Lanthanides are a series of elements from 58 (Ce) to 71 (Lu).
- Actinides are a series of elements from 90 (Th) to 103 (Lr).
Long Form of the Periodic Table
- In the long form of the periodic table, elements are arranged in eighteen vertical columns.
- Elements belonging to A and B subgroups are placed in separate columns.
- The long form of the periodic table is an extension of the modern periodic table.
Electronic Configuration
- The electronic configuration of an element is the arrangement of its electrons in orbitals.
- Rules govern the filling of electrons in orbitals.
- The electronic configuration of an element determines its position in the periodic table.
Units and Modules
- The course is divided into modules, each containing units.
- Module 1 covers topics such as the periodic table, modern periodic law, electronic configuration, atomic radius, ionization energy, electron affinity, and electronegativity.
- Unit 1 covers the periodic table, and Unit 3 covers electronic configuration.
