Atomic Number 1 2017

The atomic number of an element is equal to the total number of protons in the nucleus of the atoms of that element. The atomic number can provide insight into the electronic configuration of the element. For example, carbon has an electron configuration of He 2s 2 2p 2, since its atomic number is 6. Electron Configuration (Elements 1-20) The full lesson can be viewed by enrolling in the Year 9 Chemistry Online Course or by purchasing the Year 9 Chemistry Lesson Notes. Learning Objective In this lesson we will learn how electrons are arranged Read More.
