1. SEP Obtain and Evaluate Information Conduct research to learn more about the relative sizes, or atomic radii, of atoms. Find out how scientists define this
property, and identify specific examples. Verify the claim that atomic size tends to
decrease across a row of the periodic table.

Which of the following statements is true about energy quantization at the atomic level? electrons in the outermost orbits are the most stable. electrons in all the orbits around the nucleus have the same amount of energy. electrons in the orbit closest to the nucleus have the least amount of energy. electrons absorb or release the same amount of energy independent of the energy levels.
