Definition, properties and the identification of isotopes

Àpd 31.48 $ /h

The word isotopes are the combination of two words, one is Iso which means ''same', and another is topes which means ''places'' those elements which have the same atomic number (numbers
or proton), but different mass number are called isotopes.

In a neutral atom there is
equal numbers of proton and electron, so their chemical properties are same but
have different physical properties, so we can separate them by physical method.

Usually, mass spectrograph
is the method which is used to separate the isotopes of different elements.

Graduated and Experienced for more than 18 years, I give private lessons in Mathematics - Analysis - Matrices - Statistics - Algebra - Geometry - Physics - Chemistry - Biology, Geology to students of French program of Terminales, patent and secondary or international program IB in English (Grade 8, 9, 10, 11, 12) or entrance exams and medical university preparatory classes or 1st and 2nd university years for the academic year 2022/2023 either at home or by internet online by a very modern and professional method much better than webcam and better than on site.
The online method is easily done by a link that serves as a writing board, typing and projection more than Skype or Zoom talking about which we communicate. This method is very modernized and reliable (it's like we are in the same place) for more than 6 years I have been working by this method.
The results of my students and in particular the students of Terminale are superb with successes in mention very good and good and sometimes excellent.
Homework help for CNED students.
For more information, do not hesitate to contact me.

Passionate & empathetic teacher. I have a Master's in Physics with honors from the University of Leicester (which was featured at the time as a top 5 Physics university in the UK by The Guardian) and a - french - European School diploma in which I achieved 90% in Physics and 85% in Maths.

Helping others understand difficult topics and skills is something that I am very passionate about as an empathetic person. I have experience teaching Physics and Maths to kids from unprivileged backgrounds at the homework school in Saint-Gilles (CASG du Service Social Juif asbl) as well as 5 years of private teaching.

In my classes, I aim to:

- help students achieve better grades in exams/tests in all branches of Physics & Maths
- clearly explain and break down topics
- give context and or example applications of topics (to improve understanding and memorization)
- help with ADHD & other learning disabilities
- give practical advice for university applications (eg. UCAS in the UK) and discuss the exciting Physics research/work and projects you can work on later in life.

Physics has a plethora of useful and fascinating applications, from the detection of Gravitational Waves and Gamma-Ray Bursts to the development of novel Medical Imaging techniques and Nano-technology (eg: smartphones). It is a subject that I am very passionate about and I hope to make use of my years of experience and extensive knowledge to help you understand and love the subject! My lessons will always be tailored to the individual needs of the student, so please do not hesitate to contact me if you have questions!

Mathematics and science subjects can weigh heavily on your study career during secondary education. It is therefore important to perform well on this. This can be a challenge for many students, especially in the third grade. In my lesson I try to explain the subject matter to students based on their own course, my old course and extra exercises. The ultimate goal is that the students gain a better understanding of their course.

Je suis un professeur particulier qualifié et passionné de mathématiques et de sciences physiques (PC), diplômé de l'Université Cheikh Anta Diop de Dakar (UCAD). Mon parcours académique inclut des études en mathématiques, physique et informatique durant mes deux premières années universitaires, suivies d'une licence et d'un master en biomathématiques, où j'ai pu approfondir mes compétences en sciences appliquées.

Mon expérience en tutorat a débuté au sein de mon cercle familial, et avec plus de dix ans d'expérience, j'ai développé une approche personnalisée du soutien scolaire, enrichie par une formation pédagogique en ligne. Je propose des cours adaptés aux besoins spécifiques de chaque élève, en commençant toujours par un bilan approfondi de leurs compétences pour mieux cibler les lacunes et élaborer un programme de remédiation sur mesure.

Sur le plan personnel, je trouve une grande motivation dans le travail avec des élèves passionnés par la réussite. Leur détermination à progresser stimule mon engagement à les accompagner vers leurs objectifs. Très professionnel dans ma démarche, je me concentre strictement sur l'aspect pédagogique, garantissant un environnement de travail sérieux et structuré pendant les cours.

Ma maîtrise des programmes de mathématiques et de sciences physiques, couplée à mon expertise en biomathématiques, me permet de simplifier des concepts complexes et de rendre l'apprentissage des sciences plus accessible. Mon objectif est d'aider chaque élève à renforcer ses bases, à retrouver confiance en lui et à acquérir une autonomie dans ses études.

Je propose mes cours particuliers à Dakar, au domicile de l'élève ou à distance via une plateforme en ligne interactive, offrant ainsi une flexibilité et une efficacité égales dans les deux formats.
