I believe that the substance known as botulinum is one of, if not the deadliest toxin known. Wiki has its own page describing this toxin.
Yes, the deadliest substance known to man is botulinum toxin produced by a bacteria. It has an LD50 of .05 microgram/Kg which means for a 70 kilogram man would only need to ingest only .0035 mg to have a fifty percent shot at death.
There are lots of criteria for determining what "most deadly" mean, as mortality speed, chance of recovery, lethal substance amount, how quickly it spreads, etc. are all considerations. Some of the most lethal substances I've heard of would be VX nerve agent and phosgene gas, although there are many other lethal chemicals out there.
Researchers at the U.S. Department of Energy's Ames Laboratory made a gem of a discovery while tinkering with an unlikely material -- it's the second-hardest bulk substance after diamond.
By introducing a small amount of silicon into an alloy of aluminum, magnesium and boron, they created a material slightly harder than cubic boron-nitride, the material now ranked second. But the Ames researchers hope that experiments with other additives will make it even harder.

scientists believe that before the earth was created a single atom exploded causing a huge irruption which is called the big bang which created our solar system today apart from a galactic storm reaching speeds up to 17748 mph or a very explosive substance called napalm.
Cyanide is a very dangerous chemical. This chemical prevents oxygenation of the body from blood, killing the body. In short, blood carries oxygen, cyanide prevents blood from carrying it, and no oxygen=dead.
Botulinum toxin, caused by the bacterium Clostridium botulinum is the most powerful toxin known to mankind. It commonly causes botulism, but is also used in Botox beauty injections.
my brothers.
Pheremones.
That's totally wrong, the most toxic substance known to man is Botulin toxin, from the bacteria Clostridium botulinum. Botulin is approx 1000 times more toxic than TCDD, and TCDD is also less toxic than polonium 210. No man made substance has come close to beating the toxicity of a certain bacteria Botulin is commonly known under the trade name of "botox" so when you're having that injected into your face remember this
Chlorine is a highly reactive agent thus this indeed is chemical.
Yes, its the most reactive element known to man.
Plutonium is one of the most deadly substances known to man.
Californium is a man made chemical element.

Yes Dioxin is man made in fact it it the most most dangerous toxic poison that has ever been made by the hands of man.
Every chemical known to man, but mostly sodium chloride
Its not bad for you. There has been no evidence to suggest it is harmful to the body or mind. Albert Hoffman (the man who discovered it) used it most of his life and lived to be 102. LSD is one of the least toxic drugs known.
Plutonium is a man made chemical element, radioactive, actinoids family, unstable, metal, solid, toxic, fissionable with neutrons, atomic number 94.
Jesus?
It is difficult to determine who the most intelligent man known to man is as intelligence is subjective and can be measured in different ways. However, some individuals known for their exceptional intelligence include Albert Einstein, Leonardo da Vinci, and Isaac Newton.

No one. The air is toxic and out to get you. It's the government man.
Toxic fumes are gases that are poisonous or dangerous to people. There are different levels of toxicity, meaning some fumes ( gases ) are more dangerous than others. For instance, carbon monoxide can be present in your house. It is a toxic fume that comes from car exhaust or furnaces. In very, very low concentrations, you may only show mild symptoms like a headache or even none if you come and go a lot. But in higher concentrations it will be lethal (deadly ) and kill you. Toxic fumes generally come from factories or result from chemical processes like combustion ( in an engine ), or processing/manufacturing ( mills, oil refineries,chemical plants). It is now widely accepted that cigarette smoke is toxic, as it causes cancer, and has been linked to lung and Heart diseases. Generally, most toxic fumes are man-made.
