Easiest trick to learn Valency of Elements 1 - 30 - Dr K

In less than 2 minutes, you'll remember the valency of elements 1 - 30! We'll use 2 valency tricks - valency for the first 20 elements and valency for elements 21 - 30. The main group elements (first 20 elements) are very easy and straight forward. The transition elements (elements 21 - 30) are not as straightforward as they have multiple valency. 🕑 Here's when you'll find: 0:00 Valency of elements 1 - 20 0:40 Valency of elements 21 - 30 1:42 Hack for polar or nonpolar molecule 📺 RELATED VIDEOS: ►Lewis symbols & HONC:    • Easiest trick to learn Valency of Ele...   ►Electron configuration:    • How To write electron configuration u...   👍🏼Subscribe for more Chemistry videos 👍🏼 https://goo.gl/VXujkS * Closed captioning is available in English * 💗YOU MAY ALSO LIKE: ►Polar or not?    • How to determine if a molecule is POL...   ►Polar or not? v2    • 🌟SUPER EASY | How to determine if a m...   ►SI prefixes:    • SUPER EASY way to remember SI Prefixe...   ►Functional groups:    • Organic compounds functional groups i...   ►% concentrations:    • How to calculate percent concentratio...   ►Intro to isomer:    • Introduction to Homolog & Isomer - Dr K   ►C6H14 isomers:    • Constitutional isomers of C6H14 | Alk...   ►C3H8O isomers:    • Constitutional isomers of C3H8O | Alc...   PLAYLISTS: ►IMFs and boiling points: https://bit.ly/3zMXq6I ►O-level: https://bit.ly/3lcwsND ►Matter: https://goo.gl/ER1bP6 ►Measurement: https://goo.gl/rGoeEb ►Covalent Bonding: https://goo.gl/TDPfpS ►Chemical Equations: https://goo.gl/1LKrxj ►Organic Chemistry: https://goo.gl/XnpJVo ►Functional groups: https://goo.gl/SkWswp ►Basic Math for Chemistry: https://goo.gl/WvZH3k ►Solutions: https://goo.gl/1yjy5v ►Stoichiometry: https://goo.gl/1RXYXk Let's connect: Facebook 👉🏼   / chemsimplified   Instagram 👉🏼   / chemsimplified   Twitter 👉🏼   / chemsimplified   TikTok 👉🏼   / chemsimplified   App: https://csk.passion.io/ Website: https://chemsimplified.com/ Udemy Course: https://bit.ly/3lxuqrG 🎵 Music: Can't complain by Julio Kladniew
