Quality education can build a beautiful society. Hi, I’m Farhan Sadik. I used to enjoy chemistry from school life. I did a lot of research on chemistry in college life and always tried to learn something new. Now I’m doing B.Sc. in computer science engineering. One of the topics of my research is the periodic table. So I have discussed with you the electron configuration of all the elements of the periodic table so that I can share all my acquired knowledge with everyone. For this, I am working as a full-time chemistry writer on the valenceelectrons website. If you read every page of this website well, you will be able to know a lot of unknown facts of chemistry and gain a lot of knowledge. Good luck to everyone.
