So we all know about the carbon cycle, and the water cycle, and maybe even the nitrogen cycle. But new research has figured out there's a salt cycle, too. Problem is, that same research has found that we already broke it. Here's what...

Atoms are a lot like us - we call their relationships "bonds," and there are many different types. Each kind of atomic relationship requires a different type of energy, but they all do best when they settle into the lowest stress...

Cations, formed by electron loss, influence ionic bond strength. Smaller cations with higher charges create stronger ionic interactions

An atom or molecule that has gained or lost one or more electrons, and so has an electrical charge.

By the end of this learning object, the student will be able to: Explain the meaning of salts and their properties.14004

This video covers the difference between the properties of metals and non-metals, and takes a look at transition metals.

Electrons and Ions describes what occurs in an atom when electrons are added or removed from the outer shell using the terms ion, bonding, gain, lose, and charge.

Upon viewing the Forming Bonds video series, students will be able to do the following: Understand that matter is made up of tiny particles called atoms. Explain that atoms consist of many different types of subatomic particles including...

This video is an educational presentation on how to form compounds through understanding the charges on various ions. The viewer learns about the formation of positive and negative ions in metals and non-metals, how to predict the charge...

Learn the basics about Testing for positive ions in the first part of the lesson. How can Ions be detected? What methods or techniques are used? Find out more in this video!

This program covers the very important topic of ions and ionic charge. We begin by discussing the concept of an ion and how it relates to a neutral atom. We then discuss how to calculate the ionic charge on an atom with practical...

This program covers the very important topic of ionic compounds. We discuss how ionic compounds form and how to predict ahead of time what the chemical formula will be when given the atoms that form the ionic compound. We spend a great...

This program covers the very important topic of ionic compounds with polyatomic ions. We discuss the concept of a polyatomic ion as simply the grouping of atoms that has a net charge associated with it. We then discuss how these...

This video explains how the position of an element in the periodic table can help predict its chemical properties. The video starts with an overview of the periodic table and its organization, highlighting the separation of metals and...

In this video we'll be looking at zinc(Zn), copper (Cu), potassium (K), calcium (Ca), iron (Fe), lithium (Li), magnesium (Mg) and sodium (Na) and their reaction to water and acid. You may have noticed that most of the elements in the...
