Molecular and Ionic Compounds?

Question

Please explain me what's the difference between this compounds

Just a few days ago I knew that the compounds were joined because one is a cation and the another one an anion, there were electron transference and for me was logic because different poles experiment attraction, but then I read that exists the Molecular Compounds in which there's no exist electron transference, then how they join?

Please explain me I'm confused

Answer 1

Well, there are several types of bonds between molecules. Ionic bond is of the types and whatever you know about them is absolutely right.

Now u consider another type - Covalent bonds. As the name shows, Co Valent .... they are formed by sharing of electrons.

In this the bonding molecules share electrons, like in C-H bond, H wants 1 electron to complete its outter shell, while C needs 4 MORE electrons. So they both will not give their existing electrons. Thus they will share their electrons, and they will come closer.

Thats why carbon bonds with 4 hydrogens(H) and forms Methane(CH4).These type of compuds are called molecular compunds.

Usually Covalent bonds are less strong than ionic ones.

I hope you liked the answer. Please vote it as best answer(I took much time on this...so please !!).
