About me

Hey! I'm Steven, 20 years old and I'm studying Biomedical Science at Durham University. I love tutoring people, to put it simply. I've been working with MyTutor for over two years now and enjoy it as much now as i did at the start, working hard with each student individually to improve where they feel they need to. I'm friendly, enthusiastic and very understanding of any questions; if I hadn't had the help I hope to provide for my exams then i wouldn't be studying at Durham! Reading Biomedical science, it may come as no surprise to hear biology and chemistry are where my passions lie. However after studying them at A-Level, maths and especially english still hold a firm place in my interests. As a tutor i think it important not to spoon feed anyone; whether it be for the generic reasoning of "they wont learn anything" or my belief that at times it can be overly helpful, even condescending. I would look to guide students, help them and hint them so they acheive the answers themselves. Obviously, when an answer is needed i would be more than happy to show them the way, so they are prepared for another, similar question. I am a very patient man, and rushing students through answers is not who I am. I'd be happy to help any student who thinks i would be able to do so, and my enthusiasm for my chosen subjects is bound to rub off on anyone. Hope to see you all soon!

About my sessions

My tutorials first and foremost are based around what each student wants to cover. No matter how small or seemingly trivial, I'll prepare a session which focuses where you as a student wants to focus and never rush over anything until it is fully understood. I lean toward question based learning, purely because that was and still is how I work, as I believe the more questions you see the fewer there are that can surprise you in an exam. I like to spend time on questions, talking about common features of questions, stock answers and exam tecnique so common questions become second nature and uncommon questions are at least familiar. However, if questions aren't the thing for you, and theory is much more your style, I enjoy the more "teachy" style just as much, so i like to think an enjoyable discussion could be had on that subject. And dont worry, if you have no idea what you want to do and just want general help, I'm sure i can construct a broad enough session!

Questions Steven has answered

Explain why fluorine is more reactive than chlorine.

There are three things to consider every single time relative reactivity is unknown; atomic radius, shielding, and number of electrons. The reactivity is the halogens ability to gain an electron, so number of electrons already in the atom plays a vital role. Chlorine has more electrons so repels a reacting electron with greater force than fluorine, making it less likely to react. 

Fluorine also has fewer electron shells than chlorine, so there are fewer electrons between the positive nucleus and the reacting electron to essentiallly block, or weaken, the electromagnetic attraction. This is shielding. 

Lastly, fluorine is much smaller molecule than chlorine, and the shorter distance, or radius, between the nucleus and the electron again makes it more likely to attract the electron and react to gain a noble gas configuration.

What makes DNA molecules so stable?

The main bonding in DNA which renders the double helix structure so stable is that of hydrogen bonds. Between the complementary base pairs, hydrogen bonds connect the two strands of the helix. There are 3 H bonds between Guanine and Cytosine and 2 between Adenine and Thymine. As well as this there are hydrogen bonds between the bases and surrounding water molecules, and this combined with the even stronger phosphodiester bonds in the sugar phosphate backbone make DNA very stable.
