Hey! This is Rownak. I am just a compilation of zillions of protons and electrons just like you. My brain releases dopamine while I make something understandable to someone & you know what!? Dopamine is a symbolic representation of happiness. When someone understand any topic, the blink in his or her eyes, satisfies me. I am doing this by teaching CHEMISTRY for the last six years! So, here I am, your chemistry mentor. Thank you.
