what is covalent and ionic bonding? (1 Viewer)

[kaha167]

A simple defnition?
for a year 10 sc question
thankyou very much

Arghh how much i hate chemistry...

cheers

p.s i hate chemistry

Ionic: bond between a metal and a non-metal
Covalent Molecular: electrons are 'shared' amonst two non-metal substances.. That is about as simple as i can go dude

 

[Pwnage101]

true chemists define a 'covalent bond' as:

the ELECTROSTATIC FORCE OF ATTRACTION between a 'shared' pair of electrons and two adjacent nuclei

all chemical (inter and intramolecular) bonds are ELECTROSTATIC in nature

PS. This comes under the scinec umbrella called 'chemistry' , not physics

I think a covalent bond is the sharing of electrons, whereas in an ionic bond, the electrons are transferred, creating one atom with a positive and one with a negative charge, and these attract eachother through electrostatic forces.

And even if thats not right it's easy to think of it like that.

I thought it was suppose to be a year-10 definition, so it should be kept simple as possible.

Simply, Both are attractions between atoms. however, covalent bond is formed by the "sharing of electron(s) between two atoms" while ionic bond is formed by the "transfer of electron(s) from an atom to another".

Simple as possible hey?

When two elements from the right of the periodic table join together, it's called covalent bonding.

When an element from the left and one from the right join it's called ionic bonding - ionic becuase like stated before, they form a negative and positive ion which attract eachother, rather then a combination fo their valencies to create stable electron shells.

Covalent = strong, non-conductive

Ionic = weaker, conductive in solution.
