This document contains a summative exam in science for grade 9 students. It includes 10 multiple choice questions testing concepts in atomic structure and electron configuration. Students are asked to identify the number of electrons in the first orbital, the number of orbitals in the third principal energy level, and the group and period of an element with a given electronic configuration. They are also asked to identify orbital, electronic configuration, and the Aufbau principle from a list of options. The exam then tests students ability to write the electronic configuration of given elements and determine the element represented by a given electronic configuration. It provides the contact information for Guinbinalan Integrated School in Capiz, Philippines where the exam is being administered.
