The correct Answer is:
To solve the matching question, we will analyze each term in Column-I and find the corresponding term in Column-II. ### Step-by-Step Solution: 1. **Aufbau Principle (A)**: - The Aufbau principle states that electrons fill orbitals starting from the lowest energy level to the highest. This relates to the arrangement of electrons in an atom. - **Match**: T (Electron configuration) 2. **De Broglie (B)**: - Louis de Broglie proposed that particles, such as electrons, exhibit wave-like behavior. The formula associated with this is λ = h/mv, where λ is the wavelength, h is Planck's constant, m is mass, and v is velocity. - **Match**: s (λ = h/mv) 3. **Angular Momentum (C)**: - Angular momentum in the context of electrons is given by the formula mvr, where m is mass, v is velocity, and r is the radius of the orbit. - **Match**: u (mvr) 4. **Hund's Rule (D)**: - Hund's rule states that electrons will occupy degenerate orbitals singly before pairing up. This relates to the orientation of electrons in orbitals. - **Match**: q (Orientation of an electron in an orbital) 5. **Balmer Series (E)**: - The Balmer series refers to the spectral lines of hydrogen in the visible region. It is a specific set of wavelengths emitted by hydrogen. - **Match**: p (Line spectrum in visible region) 6. **Planck's Law (F)**: - Planck's law relates to the quantization of energy and describes how energy is emitted in the form of photons. - **Match**: r (Photon) ### Final Matches: - A → T (Aufbau principle → Electron configuration) - B → S (De Broglie → λ = h/mv) - C → U (Angular momentum → mvr) - D → Q (Hund's rule → Orientation of an electron in an orbital) - E → P (Balmer series → Line spectrum in visible region) - F → R (Planck's law → Photon) ### Summary of Matches: - A - T - B - S - C - U - D - Q - E - P - F - R
