After teaching and tutoring thousands of chemistry students over the years, I've found that the topic of ions tends to cause tremendous confusion (and is generally poorly understood).This is one of those fundamental topics that must be understood properly if students are going to learn about balancing equations, stoichiometry and advanced level chemistry later in in school. I created this resource booklet as a very clear way for students to understand the following: • What the period and group numbers tell us about the structure of an atom • What anions and cations are • How to use the group number of an element to figure out what kind of ion it will form Complete with full colour images, activities and answers; this booklet finally offers a clear and comprehensive explanation of this fundamental topic in chemistry. At the end there is also a link to a website, where students can take this topic to the next level and learn about ionic bonding and the formulae of ionic compounds. I've set the price at 2 pounds because this resource took a lot of time to create, and is of a very high quality.
