Question

Let's go over the foundation of atom and its structure!

Answer 1

Version#2

Answer 2

?

Answer 3

Yay

Answer 4

ayy

Answer 5

I'll also post the link for version 1

Answer 6

Great! Now we are into electronegativity folks! And how electronegativity of different elements induce different levels of attraction in covalent bonding!

Answer 7

For version 1: http://openstudy.com/study#/updates/55ca2191e4b0c5fe980533aa

Answer 8

And how the resulting shape (for example tetrahedral/linear) determines whether its polar or non polar compoundXD

Answer 9

Just to recap people here know covalent bonding stabilizes the participating elements.

Answer 10

Convalent bonding is different from ionic bonding in that they "share" their properties as opposed to exchanging electrons.

Answer 11

Which is the case in ionic bonding.

Answer 12

Ok

Answer 13

Answer 14

Every element has an assigned electronegativity. This electronegativity, when bonded, determines the direction of "polarity" dependent on the extent of electronegativity.

Answer 15

For example, take the water molecule

Answer 16

Despite having two identical bonds in a V shaped manner, the difference of electronegativity between hydrogen molecule and oxygen molecule are slightly directed off to the side, hence making the water polar with dipole dipole attraction.

Answer 17

This further serves to explain why water drops are not power like.

Answer 18

interesting, another new thing I learned

Answer 19

δ- symbol for electronegativity

Answer 20

Oh by the way we should cover isotopes here too.

Answer 21

Who here knows what isotopes are?

Answer 22

Isotopes indeed differ in the number of neutrons present. However protons don't change so they find the same spot in our periodic table.

Answer 23

However drop or rise in the number of neutrons also affects electron configuration as well.

Answer 24

what are isotopes?

Answer 25

Isotopes are different versions of the same element.

Answer 26

For example 99% of carbons in our atmosphere are carbon-12

Answer 27

but there are radioactive carbons like carbon-14.

Answer 28

Mind you, they have the same number of protons, but it's just that they have different number of neutrons.

Answer 29

Now I get it, yay :)
