Question

Electromagnetic radiation of wavelength 242 nm is just
sufficient to ionise the sodium atom Calculate the ionisation
energy of sodium in kJ mol
–1

Prerna Bansal · Accepted Answer

Energy of sodium (E)

= 4 947 × 105 J mol–1 = 494 7 × 103 J mol–1 = 494 kJ mol–1

Electromagnetic radiation of wavelength 242 nm is just sufficient to ionise the sodium atom. Calculate the ionisation energy of sodium in kJ mol –1 .
