Ionic bonding?

[SS4]

Well, a number of things could happen, but the likelihood is you'll form a solid of oxidation state zero where the electrons are spread between the many nuclei within the solid. The free electrons will be very reactive. See the reaction of Na (s) with water, forming NaOH (happy ionic compound) and H2 (stable covalent compound).

Both atoms being one away from a full shell will form a covalent bond, eg Cl2.

When hydrogen is one of them, e.g. HCl there is a bond which has both ionic and covalent character!

Same with some of the Be compounds due, I believe, to the charge/atomic radius ratio.

However, I am straying off topic (unlike a free radical )

Wow. I'm just waiting for someone to put up a plea for calculus help... Can you imagine the reaction?! :roll:

My son has just started an IGCSE course. Sciences were never my forte at school.

GCSE, just started yr9. i've only had about three hours of this....

can i say to all, please don't judge my intelligence on this i normally am more switched on, promise!

Ah youve got ages to learn! Never be afraid to ask on here should you ever get stuck again.

leave one integrate the other, minus the integral of the integrated one times the other differentiated?

Repeat until you get an even texture, and peaks start to appear...

Ugh, dot-cross disgrams! Such a misrepresentation of the quantum beauty of orbitals!

The full outer shell thing is a way of describing the stabilisation of electrons by their occupation of lower energy levels in a molecule or ionic lattice. The shells thing actually relate to electrons at differing energy levels in different shape orbitals, and the likelihood of finding an electron at that distance and orientation from the nucleus. Electrons are best described as waves rather than particles anyway, and actually it is legitimate to describe the negative charge as being distributed in a non-uniform field. The "position of the elctron" is really best described as "the region of highest concentration of negative charge".

In this case of Mg and Cl, forming an ionic compound, the lowest energy (therefore favoured) state is where the highest energy electrons of Mg are transferred into the unfavoured "almost full" energy levels (orbitals) of Cl.

That is degree level Chemistry really though!

And don't I know it !! [ Topic covered in 1st year of degree ]

Just reading though this thread has blown my brain, I was always never to hot on science espicially stuff like this.

 

[valenta]

Probably my biggest problem with sciences at school was that I had no interest in them. No desire to know how "stuff" worked, and hoping none of my former teacher's are on this forum, almost everything they said just went right through me. Out of all my sciences chemistry had to be my weakest, and all the chemical formulas blew my brain!

I can cope with science, but I absolutely hate it. Science, and maths too.

 

[valenta]

and maths too.

Don't get me started!

I am exactly the same!

I absolutely loathed Chemistry, it was the biggest load of tripe I'd ever done
in all my life. I'm sure plenty on here will disagree with me, but when on earth am I going to need to know what happens when hydrochloric acid is poured on a metal, or zinc and carbonate react to make some sort of equation or another......I thought it was boring, long and a great waste of time to boot, but as I can see from this thread there are plenty of members on here who do enjoy Chemistry. There's nothing wrong with that, if you're good at it, if course you'll enjoy it, but I was grade one rubbish and Chemistry was my downfall!

I liked Physics, and I found Biology easy. Maths........was a disaster.

Chemistry is one of the most versatile subjects you can possibly take. And one of the most versatile degrees you can possibly do career-wise. It misses the point somewhat to simplify it down to "what happens when this reacts with this" just as it misses the point to say "what does it matter if the cavaliers lost to the roundheads" in history. The study of the subject is as much about learning an analytical approach, a problem-solving mindset, advanced numeracy and developing a suite of skills, than it is about learning about reactions. It did help that I understood and enjoyed the subject as well of course.

I started as a graduate as a bench chemist but am now in sales and marketing, working for a company which is involved in chemicals but I am very much on the commercial side in another division.

I think with chemstry its much like maths and art, you can do either do it or you cant.

TNT, I believe.


I was alright at Chemistry at school, but despite only being a couple of years ago, I remember very little of it now.

Not too hard to make TNT, well, its simple chemistry. however it has this habit of exploding during the manufacture process unless you are an expert
