ISB G10 Integrated Science 24-25 Chemistry 1: Periodicity Student Content Guide Inquiry Question: How can periodic trends be used to predict the behaviour of matter? Big Understandings: ● The periodic table is a powerful tool for understanding the properties of elements and their reactivity. ● Atoms consist of subatomic particles (protons, neutrons, and electrons), and their arrangement influences the behaviour of elements. ● The chemical activity of metals can be investigated and compared to establish trends in reactivity. Skill Focus: ● Developing and interpreting models (e.g., atomic structure and periodic table trends). ● Collecting and analyzing experimental data to investigate chemical activity. ● Drawing conclusions about patterns and trends in chemical behaviour. Science Concept Recognizing that elements in the same group of the periodic table have similar properties Core Knowledge Questions Elements are organized into groups and periods in the periodic table. Elements in the same group share similar properties due to their electronic configuration. How are elements organized in the periodic table, and what does their arrangement tell us? I can define groups and periods in the periodic table. Struggling I can explain why elements in the same group have similar physical properties. Struggling ISB G10 Integrated Science 24-25 I can compare elements in the same group regarding reactivity and physical properties. Struggling I can identify trends in properties within groups and periods. Confident Atoms are made up of protons, neutrons, and electrons. The arrangement of electrons in shells determines the chemical properties and placement of elements in the periodic table. What is the structure of an atom, and how are electrons arranged? I can describe the basic structure of an atom. Struggling I can identify subatomic particles (protons, neutrons, and electrons). Struggling I can explain the nucleus and electron shells. Struggling I can determine how electrons are arranged in shells and/or energy levels. Struggling Describing the structure of atoms in terms of electron shells I can describe the SPDF configuration and apply Aufbau, Pauli’s, and Hund’s principles. Struggling I can explain how the electronic structure determines an element’s position in the periodic table. Struggling I can explain how electronic configuration gives elements their spectral fingerprint and can use this to identify elements. Struggling I can describe how electron configuration explains the trends in the periodic table for: Ionization energy Struggling Atomic radius Struggling Ionic Radius Struggling Electronegativity Struggling Investigating the chemical activity of metals Metals exhibit different reactivities depending on their position in the reactivity series.
