Study Notes
Main Focus of Module-1: PERIODIC PROPERTIES
- Explores the trends and patterns in elemental properties within the periodic table.
- Analyzes periodic trends such as atomic size, ionization energy, electronegativity, and electron affinity.
Tendency to Attract Bonding Electrons
- The property associated with an atom's tendency to attract a bonding pair of electrons is known as electronegativity.
Atom Size Determination
- The size of an atom is primarily determined by atomic radius, which is influenced by the number of electron shells and the effective nuclear charge.
Ease of Electron Loss
- The measure of how easily an atom can lose an electron is called ionization energy.
Effective Nuclear Charge in Multi-Electron Atoms
- Effective nuclear charge refers to the net positive charge experienced by an electron in a multi-electron atom, accounting for both the protons in the nucleus and the shielding effect of other electrons.
Orbital Energy Variation
- The variation in s, p, d, and f orbital energies is determined by electron-electron interactions and the differences in the principal quantum number alongside the shape of the orbitals.
Increasing Ionization Energy Trend
- The trend of increasing ionization energy across a period is mainly due to increasing effective nuclear charge, which pulls electrons closer to the nucleus.
Ability to Form Negative Ions
- The property of an atom that indicates its ability to attract an additional electron to form a negative ion is known as electron affinity.
Influence on Atom Size
- Factors influencing atomic size include nuclear charge, the number of electron shells, and the shielding effect caused by inner electrons.
Measure of Electron Pair Attraction
- The ability of an atom to attract a bonding pair of electrons is quantified by its electronegativity.
Repeated Factors Influencing Atom Size
- Again, the primary influences on atomic size are nuclear charge, the number of electron shells, and electron shielding.
Trend in Ionization Energy
- The increasing ionization energy across a period is again linked to effective nuclear charge, reinforcing the pull on the outer electrons.
Ability to Attract Additional Electrons
- An atom's ability to attract an extra electron, forming a negative ion, is defined by its electron affinity.
Determinants of Orbital Energies
- Orbital energy variations in the periodic table are influenced by nuclear charge, electron configuration, and the degree of electron shielding in various sublevels.
