why is graphene so strong...i dont understand

i read somewhere:

"The free delocalised electrons flow through a lattice of positively charged carbon atoms and the electrons are attracted to the positive charge of the carbon atoms which means that there are strong electrostatic forces of attraction within the graphene. "

 

is this why graphene is so strong, .....i found this is on yahooanswers and it was apparently answered by someone in Yr11, so i dont really trust it but it really hard to find why graphene is so strong.

i dont understand what some websites are on about

Understanding bond strength and length

Which of the following has the strongest bond:

CH4

NH3

HF

H2O

Based on the lecture given by my teacher I know that the more electrons involved in a compound the shorter and stronger bond they have, thus is seen drawing the Lewis Structure. But, Since all of these only make a single bond I have no idea how to tell which one has the strongest bond.

Bonding Angles and why they are different.

I understand the prediction of bonding angles, but the significant differences in the actual angle vs the VSEPR angle is what confuses me.

Why do bond angles in VSEPR not always match the actual angle?

Why does Methyl chloride have a larger angle that 109.5 even though it is tetrahedral?

Order Molecules in terms of increasing Polarity

Order Molecules in terms of increasing Polarity

 

CF4, CH2F2, CHF3, CH3F

 

I can write their molecular geometry but I don't know how exactly I'm supposed to compare them together ... for instance, in CH2F2 , 2 F can be on any side of tetrahedral molecule!

How to explain the increasing of ionization energies?

The ionization energies increase monotonically for B, C, N and also (separately) for O, F, Ne. However IE(O) < IE(N). Explain these two facts.
