In chemistry, frequency refers to the number of occurrences of a repeating event per unit of time. It is a crucial concept in various chemical processes and is particularly important in the study of atomic and molecular spectroscopy.
Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles.
