Introduction. These questions are designed to help you to develop your mental models (pictures in your head) of ions. Being able to think about ions in different ways will help to develop your understanding of ionic structures. Use the icon in the margin to find out which level of understanding the question is developing. Macroscopic:
Use the periodic table to write the name and formula (including charge) for the ion formed from each element in the table below. Element Name Formula Fluorine Calcium Oxygen Polyatomic Ions 9. What is a polyatomic ion? 10 . Is the following sentence true or false? The names of polyatomic anions always end in -ide. 11.
Monatomic Ions. Use a periodic table to complete the table below: Element Name. Element Symbol. Ion Name. Ion Formula. 1. sodium.
How To write an electron configuration: Determine the total number of electrons to be represented. Use the Aufbau process to fill the orbitals with electrons. The Aufbau process requires that electrons fill the lowest energy orbitals first. In another words, atoms are built from the ground upwards.
Identification Of ions And Gases. 1 Four gas jars each contain one of the gases ammonia, chlorine, hydrogen chloride and oxygen. A strip of damp blue litmus paper and a strip of damp red litmus paper are placed in each jar. In which gas jar will both the damp blue litmus paper and the damp red litmus paper change colour?
This worksheet presents a widely used system of nomenclature for ionic compounds. There are two types of metal cations with different naming conventions discussed separately. fixed charge (single charge) cations. variable charge (multiple charge) cations.
