Hi, is it true to say : Addition polymers have monomers that are alkenes, and condensation polymers have monomers that are not alkenes, but that have two functional groups per molecule.?
Like if I was given a monomer, and asked if it will form addition or condensation polymers, if I see an alkene functional group ( double bond ) can I straight away conclude that it will give addition polymers?
Yes,you are right.
And for condensation polymers there must be a functional group on both ends of the monomers for example for nylon the monomers are DIamine and DIcarboxylic acid and they both have functional groups at both ends.

Sorry I'm new to this.. can you please explain why are we using Neon while working for Argon? o_O
Read chapter 3 from Roger Norris book. Page 40 :)
Else,
We can do this for any element, BUT, we must use only noble gases in the brackets. I call this thenoble gas simplification. In this method of writing electron configurations, the last noble gas before we get to the element of interest is the noble gas we put into the brackets. For instance, for the element aluminum we write

Sulfur [Ne]3s23p4
Chlorine [Ne]3s23p5
Argon[Ne]3s23p6
Potassium[Ar]4s1
Calcium[Ar]4s2
We may NOT use any element in the brackets, only noble gases.

Actually i don't have that book I'll buy it soon In sha Allah.
Can you please specify a reason for using the last noble gas? o_O
is that true that last noble gas electronic configuration will be similar to the initial electronic comfiguration of the next element therefore we use them in brackets? I'm just guessing, correct me if I'm wrong..

JazakAllah.

Yeah, not next element, but the next period until other Noble gas.
Didn't you got that explanation?
