Hi all,
I have critical question i need to know.
1- for ( CF4) the angle is less than 109.5, then why it is in the 4-pyramid equals to 109.5
2- how "Avogadro constant" was calculated?
3- could any one advise for scientific links in chemistry and science that i could read and post questions rather than edaboard which i like most.
thanks alot
