Atomic structure; Dr. Mlelwa

This consist the first part of advanced level general chemistry, that is to say, atomic structure. We will discuss several concepts from discovery of sub atomic particles, calculations of RAM, hydrogen spectrum and its calculations, quantum theory and its calculations, atomic theory with their shortcomings and finally electronic configuration of different elements, charged atoms and compounds.

About instructor

Dr. Mlelwa

Dr. Mlelwa is an experienced online tutor in biology and chemistry from ordinary level to advanced level. His highest level of education is two years of doctor of medicine (MD) at Muhimbili university of Health and allied science in from Nov 2018 to Sept 2020. There after he failed to continue with Doctor of Medicine Studies due to several reasons which are out of scope of this description. He started online teaching since January 2020 in his YouTube channel (Dr.Mlelwa Lectures) by that time he was still a medical student dreaming to become one among the best tutor in medical studies, that's why he called the channel Dr. Mlelwa Lectures, comparing to Dr. Najeeb Lectures who was one of his role mode. His good performance, being the second best boy in advanced biology examinations national wise in 2018, made him one among most interesting online tutor, having influence to different students inside Tanzania as well as abroad.
