How do you determine the valence energy level when looking at a periodic table?

AI Thread Summary
The valence energy level can be determined by examining the periodic table, where the group number indicates the number of valence electrons. Each period corresponds to a different energy level, with the number of shells increasing as you move down the table. The valence energy level reflects the number of electron shells surrounding the nucleus. By knowing the distribution of electrons in these shells, one can ascertain the total number of shells present. Understanding these concepts is essential for grasping the behavior of elements in chemical reactions.

How do you know how many valence energy level you have by just looking at the periodic table?
because you know that the group number tells the valence electrons right. :)
so what about valence energy level? :D

Well, a valence energy level is the number of shells present, and if you know how many electrons are in each valence shell, you can determine the amount of shells there are.

Thread 'Confusion regarding a chemical kinetics problem'

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
