‘Ionisation energy’ is the term used to describe the amount of energy it takes to remove an electron from an atom to form a positively charged ion. It is usually represented by the unit kJ/mol, meaning it...

When approaching a question like this, it’s important to identify the two compounds that we are dealing with first. Sodium is an alkali metal, and therefore the metallic structure that it forms comes from...

The number of moles is related to the amount of a substance we have. If we were to use the number of particles, the numbers would be huge and impractical to use. So, Avagadro's number provides us a link w...

Bonding in chemistry involves the transfer or sharing of electrons. In the case of ionic bonding, one or more electrons are transfered from one atom to another leading to charged fragments, one that is po...

Let’s start be thinking what exactly is a reaction. It takes place as an interaction between two or more particles. For that to happen, they must get close. Really close. And fast. Fast because otherwise ...
