Question

3. Write Lewis structures for the following. What molecular shape does each have? Circle the structures you believe to be polar. What is they hybridization around the central atoms? a. HNNH b. PCI c. Sicu d. So, e. CH2Br2 4. Describe how the movement of electrons about a hydrogen atom gives us a line sprectrum. (Bohr model)

Answer 1

4) When radiations passed through H-atom then electron absorb some radiations and get excited from lower shell to higher shell. When electron come back to initial state then it emit radiations and line spectrum is observed.

5) For, third shell n=3, thus l=0,1,2

Thus, 3s,3p,3d orbitals exist in third shell.

6)Shortest wavelength :

X-rays

Ultraviolet

Visible

Microwave

Radiowave

Longest wavelength

7) X-ray has high energy because energy is inversely proportional to wavelength.
