Use the electron dot formula of sulfur difluoride to predict its molecular shape

• Bent

• linear

• trigonal planar

The Bohr model of the atom proposed that electrons move at fixed distances from the nucleus and that the energy of the electron is related to its orbit.

What discovery contributed to the development of this atomic model?

• Electrons can flow freely through metals making metals good conductors.

• Elements have characteristic wavelengths of light emission and absorption

• Noble gas elements are much less reactive than most other elements.

• Electrons exhibit properties of both particles and waves.
