The exam includes short, one-mark questions requiring students to identify elements by group and period, explain reactivity and conductivity using the periodic trends, and select correct options from a provided table diagram. It also tests understanding of atomic structure by using protons, neutrons and electrons to determine mass, atomic number, mass number, group placement, isotopes, positive ions and negative charge in an ion model.","The Periodic Table  \nQuestion paper 2  \n\n| Level | IGCSE(9-1) |\n| --- | --- |\n| Subject | Chemistry |\n| Exam Board | Edexcel IGCSE |\n| Module | Single Award (Paper 2C) |\n|
