Question

What wavelength of light (in nm) is involved for an electron to change between these two lever in hypothetical element two energy lever of 282kj/mol.

Answer 1

Answer:

We know ∆E = hc/√

where h is Planck constantll and c is speed of photon √ is wavelength

∆E =282kj/mol = 282000j/mol

h= 6.6×10³⁴j/s

c= 3×10^8m/s

√= hc / ∆E = (6.6×10³⁴× 3×10^8)/282000

wavelength= 7.02×10²¹m
