I would tend to be very wary of that particular site;

what is the Most Dangerous Chemical or poison in the world?

Why not now consult the Merk Index for all the chemicals suggested and find the one with the most lethal dose. I think it's called LD50 or something like that. Tally the results and then write a nice summary quantifying (like Chemists do) the results from least to most. I suggest finding the top 10 quantifiable most toxic man-made compounds (or 10 of the most . . .) to get practice doing real chemistry. Also if you don't mind, kindly explain why chemically, what chemically, causes these substances to be so toxic.

For example, purines and pyrimidines are extremely toxic because they have similar structures to DNA and thus have the capability of interfering with DNA replication. Is this group of compounds in a list of "most toxic"?
