Chemical Bonds: Dots-And-Cross Diagrams ⚛️ GCSE Chemistry Learning & Revision

from REVISE GCSE Chemistry - A podcast by Seneca Learning · host Seneca Learning

In this episode, we discuss dot-and-cross diagrams as a method for visualising covalent bonds, which involve the sharing of electron pairs between atoms. Atoms form these bonds to achieve a full outer electron shell, typically containing eight electrons. Single covalent bonds consist of one shared electron pair, as seen in chlorine (Cl₂) and water (H₂O), while double and triple covalent bonds involve two and three shared pairs, respectively, with oxygen (O₂) exhibiting a double bond. These multiple bonds are generally stronger and require more energy to break than single bonds.Don't miss out on subscribing for more educational content tailored to help you succeed in your exams. Perfect for AQA, OCR, Edexcel, CIE and WJEC exam boards.⁠Click here to see all of our GCSE Chemistry content!
