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:
Write a ground state electron configuration for these ions. Remember that ions have a change in the total number of electrons (positive have lost electrons and negative have gained).

The names of the ions in Table 3 with only 1 oxygen all have a common format, consisting of a prefix, a root and a suffix. Circle, in Table 3, the prefix and suffix that they all have in common.
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.
The atoms in each unique element have a specific number of protons. For example, oxygen has two atoms so its atomic number is 2. Iron has twenty-six protons in its nucleus so the atomic number is 26. Scientists can identify an element by its atomic number on the chart. Conclusion. Atoms, the tiniest unit of matter, make up all things.
Aims of this worksheet: Practicing the basics of ionic chemistry. Consolidating how to determine the charges of ions. Consolidating determining the formulae of simple and complex ionic compounds and ions/ 1. (9 marks) 2. (a) When two ions join together it is called an. (b) A positively charged ion is called a .
