Definition, properties and the identification of isotopes

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 in mathematics and physics, I offer my help to students who encounter difficulties in these two subjects. My approach is to review with them the key points of the lessons and to assist them in their homework, whether at home or through online sessions via webcam.
Do not hesitate to contact me for a first request; I usually respond within 24 hours.
My goal is to help the student understand his course and his exercises, and to guide him on the right path so that he can succeed in his school or university year. I support students of all levels, from 14 years old to the second year of university, in the fields of science, economics or any other field where courses in mathematics, statistics, computer science and physics are exempted.
Classes can be given at home (with a price including the class and travel expenses) or by webcam (with a specific price for the online course).
For rehearsal sessions, I generally recommend between 1 and 2 hours per week, and up to 10 hours per week for intensive review and refresher courses.

Hi there,
I offer tutoring for math and science subjects here.
Regardless of whether it's school, university or work - having to learn to pass a subject is neither fun nor much point, as you'll soon forget most of it.
But how can it be better?
I have experienced several times how much of success depends on the emotions associated with learning. That's why I'll try to create an environment in which you feel free to make mistakes - because mistakes are important for learning! I rely on understanding, patience and curiosity to develop a positive relationship with learning rather than applying pressure.

Following the neurobiologist Gerald Hüther, I see the art in setting just the right big challenges to be exciting but not frightening, so that you automatically develop joy in discovery.
I would be happy to have an introductory meeting in order to take your needs and wishes into account from the outset.
Background information about me:
I am a qualified engineer (mechanical engineering) with 3 years of work experience, as well as a master's degree in bionics (cross-sectional discipline between biology and engineering) and a PhD in environmental protection of mountain regions. I was active as a youth leader at the Alpine Club.
I have been giving tutoring lessons on the side ever since I was at school.
I am pleased to meet you.

80% of my students got accepted in the 2025 exam, I am sure I can help you out in the 2026 exam!

TU Delft is Europe's most prestigious university for aerospace studies, preparing some of the best engineers. However the selection procedure is tough and demanding, and only those prepared have a chance to succeed.

As a TU Delft student, I know from first hand how stressfull this process is, and can therefore help you succeed in the preparation of these exams. I have previous experience as a tutor back in high school, helping students improve their grades from Cs to As.

Moreover, I have an extensive knowledge on the subjects tested on these exams, having taken them myself, completed the courses at university with excellent grades and teaching over 10 students for the entrance exam.

Throughout the class, I will use a presentation to explain the main concepts of each exam (Maths, Physics and Aerospace Engineering), focusing on those subjects the student is struggling with most. After this, I will help the student complete some practice excercises, and then assign extra practice to complete on their own time. These exercises will then be reviewed in the following class to ensure the topics have been understood.

I am looking forward to help you in your journey as an aerospace engineer!

Do you want to learn chemistry? Do you find it difficult and think the subject is impossible?
In the following Chemistry classes, you'll learn from the basics and progress until you fully understand the subject. I'll teach you using techniques and strategies that make the subject easy, simple, and fun for you, so you'll enjoy the time we spend learning.
Like you, I'm young and I understand the difficulties involved in studying a subject like Chemistry. However, I've found methods and ways for you to learn from the most basic to the most advanced, and believe me, you'll learn a lot.

Hi I'm a college student, I have advanced knowledge in subjects like, algebra, calculous, math in general, physics, and some statistics. Also, I'm a native Spanish speaker, so I can also help you with grammar, pronunciation. My main goal is to help you understand the topics that you struggle with, because in my experience, sometimes what you need is a different approach of how things are done rather than it being too difficult.
