Periodic table and atomic structure 2.2

Multiple Choice

Which of the following statements best describes how electron configuration gives rise to trends in the periodic table?

• Electron configuration determines the arrangement of elements in the periodic table, which leads to recurring trends in their chemical and physical properties.

• Electron configuration only affects the atomic mass of elements, not their trends.

• Electron configuration is unrelated to the periodic table trends.

• Electron configuration only impacts the color of elements.
