I also have to discuss covalent and ionic bonding in 1500 words...It's over 20 years since I did chemistry at school and what does science have to do with equine business which is what i'm studying...Does anyone have any useful advice PLEASE

Hydrogen is atomic number 1, and helium is 2. And Lithium, Sodium, Potassium, Rubidium, Cesium, Francium are the far left hand column. I did chemistry A-Level and thats pretty much all I can remember!
Ionic bonding is like NaCl, where one atom donates an electron to another, but covalent is when they share electrons like CO2, I suggest Wikipedia! You can't copy or import one...but you can look at one for reference ;)

It's been 40 years for me since I had to deal with the periodic table,but it is so clear and precise that once you study it you'll never forget the principle.
What is impossible for me ( or most people)is to remember the symbol,atomic weight/number of each elements.
Unless your professor is Simon La Gree,I suspect that he/she wants you to compile the table from a list of elements.
It is pretty easy,since the elements are listed in rows according to the number of atoms that they contain,starting with Hydrogen who has one atom.
The trick is deciding which class/column an element belongs to (gases,metals,etc.)and you can research that.
I can't help you with the other question,but I'll tell you that many courses seem unrelated to your final goal,but the provide a base for you to learn other things.

Wikipedia will be a good start for bonding ... I suggest you get started on that periodic table .... how will they know you haven't copied or imported?
