From the survey of my weekly JC1 and JC2 A-Level H2 Chemistry Tuition Classes, i realised that some students face challenges in drawing the Shapes of Atomic Orbitals in their Junior Colleges (JCs) lectures as well as school tutorials. In fact, it is very easy to draw them if you understand the concepts behind these Atomic Orbitals.
Atomic Orbital is basically a region of space around the nucleus in which the probability of finding a particular electron is the greatest i.e. about 98% chance of finding an electron.
Electrons can occupy four types of orbitals (s, p, d and f orbitals) that differ from each other in shape and in their orientation in space.
For Cambridge A-Level H2 Chemistry syllabus (refer to Singapore Examination & Assessment Board), you will only be tested on drawing the shapes of:
- s orbitals: spherical shape
- p orbitals: dumb-bell shape
- d orbitals: 5 different types of orbitals (tested in the Year 2017 new syllabus code 9729)
At the end of this video, you will learn the strategy to draw the s, p and d atomic orbitals effectively.
