Presentation transcript:

Aim: How are an atom’s electrons configured? Electromagnetic Spectrum -the total range of light including gamma rays, x-rays, ultraviolet, visible, infrared, microwaves, and radio waves. Orbital- region where electron can most likely be found. Ground state- when electron is in a state of lowest possible energy Excited state- when electron acquires additional energy. An electron can only absorb a discrete, or fixed amount of energy that would allow it to move to a higher energy level.

Aim: How are an atom’s electrons configured? Emission Spectrum- visible light produced by electrons. Each atom has its own distinct pattern of emission lines (or bright line spectrum), and these spectra are used to identify elements. Electron configuration-distribution of electrons

Aim: How are an atom’s electrons configured? Essential Questions: Explain how the wavelengths of light emitted by an atom provide information about electron energy levels. How did Bohr explain the presence of line-emission spectra? Compare the quantum models of Rutherford an Bohr.
