Explanation:

Question 9

The energy of a photon is related to its wavelength by the formula \(E = \frac{hc}{\lambda}\), where \(h\) is Planck's constant, \(c\) is the speed of light, and \(\lambda\) is the wavelength. Since \(E\) is inversely proportional to \(\lambda\), a shorter wavelength corresponds to a higher energy transfer. Line A has the shortest wavelength among the labeled lines.

As atomic radii decrease across a period (from left to right in the periodic table), the effective nuclear charge increases. This stronger attraction for electrons leads to an increase in electronegativity (the ability of an atom to attract bonding pairs of electrons) and an increase in ionization energy (the energy required to remove an electron from an atom).

Answer:

a. Line A
