Question

Explain the variation of max with particle size gold nano particles

Answer 1

Answer:

Explanation:

He2 molecule does not exist since the molecular orbital theory states that bond order of a element is given by Nb-Na/2 in He2 the 4 electron are accomadated in sigma 1s and sigma star 1s therefore Nb - Na =0 since bond order cannot be zero therefore it does not exist

Whereas in case of H2 molecules enter in sigma 1s orbital therefore bond order is 1.

Answer 2

The optical properties of spherical silver nanoparticles are highly dependent on the nanoparticle diameter. ... Smaller nanospheres primarily absorb light and have peaks near 400 nm, while larger spheres exhibit increased scattering and have peaks that broaden and shift towards longer wavelengths (known as red-shifting).
