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 ...

Na has more electron shells/ energy levels than Li. This means that Na has a greater atomic radius than Li. Therefore, the outer shell electron in Na experiences a weaker nuclear attraction than in Li. Le...

There are 5 main factors that affect the rate of reaction. 1. Concentration: Increasing the concentration increases the frequency of collisions between particles. 2. Surface Area: Increasing the surface a...
