With MCAT tutoring from MedSchoolCoach, we are committed to help you prepare, excel, and optimize your ideal score on the MCAT exam.
For each student we work with, we learn about their learning style, content knowledge, and goals. We match them with the most suitable tutor and conduct online sessions that make them feel as if they are in the classroom. Each session is recorded, plus with access to whiteboard notes. We focus on high-yield topics if you’re pressed for time. If you have more time or high-score goals, we meticulously cover the entire MCAT syllabus.
The ‘Z’ in nuclear notation stands for atomic number, or the number of protons in the nucleus of the atom. Each proton has a mass of 1 atomic mass unit (amu) and a positive charge of 1.6 x 10-19 coulombs. The charge of a proton is known as the elementary charge and is written as ‘1 e‘ or, more commonly, simply as ‘+1’. Also, because the proton is the only charged subatomic particle located in the nucleus (neutrons have no charge), atomic number is equal to nuclear charge (the charge carried by the entire nucleus).
It is important to note that an element’s identity is defined in terms of its atomic number. Carbon atoms may have six, seven, or eight neutrons, but they always have six protons. Further, all atoms with six protons are carbon atoms. So, if you know an atom’s identity, you can determine its atomic number, and vice-versa.
