As we all know that when we breaks the law of nature something happens wrong. Same condition is with the predioc toxic elements. If we make there use in wrong way they may be harmful to us therefore according to there harm effect we divide these elements into a criteria. Those that are toxicity, radioactive or highly reactive. Some even fit all three categories.
The thirty or so heaviest elements are all radioactive to some degree.I have skipped a bunch of these and gone for the most exciting toxic elements.
Mass: 51.996 u
It is also one of the elements that is essential to most higher organisms. But chromium has a dark side. In one of its forms chromium becomes a genotoxic carcinogen – that is something that can interfere with your DNA , increasing your chances of developing cancer.
Lead used to be used for everything; paint, eating utensils, toys and water pipes just for starters.Then someone noticed it was highly toxic elements.Whilst it might not be the most toxic elements it is probably the most likely of these nastiest you’ll come across
In high enough doses lead can be lethal. Symptoms include vomiting, staggering, weakness, seizures, coma and death.But this is rare, it is long term exposure that gets most people.Whilst still serious in adults, lead poisoning is particularly destructive in children.This is because it stunts the developing nervous system leading to irreversible damage.In short lead can permanently reduce your IQ.
Inhalation: High concentrations of this gas can cause an oxygen-deficient environment.Individuals breathing such an atmosphere may experience symptoms. It include headaches, ringing in ear,drowsiness,unconsciousness,vomiting and depression of all the senses.
Welding produces fumes that are toxic when inhaled.It beryllium is a welding material of concern.Welding fumes cause lung impairment, lung disease, cough, asthma, and lung carcinoma.Eye and skin irritation, malignant melanoma, and negative reproductive effects are also reported.
There a common all known fact is that mercury is only metal that is liquid in room temperature.Commonly it is known as quicksilver and was formely named hydrargyrum.It is used in thermometers,manometers,fluorescent lamps and other devices.
Most of its compounds are extremely toxic.Mercury can be absorbed through the skin and mucous membranes and mercury vapors can be inhaled.So containers of mercury are securely sealed to avoid spills and evaporation.As we see in history Colex plant releases the mercury in the one of the largest releases.The effects of mercury include damage to the brain,kidneys and lungs.Its poisoning can result in several diseases,including acrodyina,Hunter Russell syndrome and Minamata disease.
Arsenic is a metalloid that has various allotropes and used in many forms but only the gray form is important to industry.It is also used in car batteries in the metallic form is in the alloys of lead.It is the second most commonly used semiconductor.Its trioxide compounds used in the production of pesticides,herbicides and insecticides.
The main consequence is intense gastric distress in which everything goes wrong with your gut.It include vomiting, diarrhea and bleeding, and plenty of pain.Death often follows within hours.
Fluorine is the most electronegative element in the periodic elements.And that’s the reason why it reactive easily with other elements to form useful as well as harmful substances that may be toxic to the environment.
Chlorofluorocarbons(CFCs) are one of the most toxic gases that are harmful for ozone.It create a unbalance in the ozone reaction as it is highly reactive that cause ozone depletion.
Cesium metal is highly explosive in the presence of water.The hydrogen gas produced by the reaction is heated by the thermal energy released at the same time.It causing ignition and violent explosion.This can occur with other alkali metals, but cesium is so potent that this explosive reaction can be triggered even by cold water.
It is rare and highly radioactive metal with no stable isotopes, polonium is chemically similar to selenium and tellurium.
Polonium is highly dangerous and has no biological role. By mass, polonium-210 is around 250,000 times more toxic than hydrogen cyanide.This reactivity makes polonium on of the toxic element in the periodic table.
Plutonium is the element with the highest atomic number to occur in nature.Trace quantities arise in natural uranium-238 deposits when U-238 captures neutrons emitted by decay of other U-238 atoms.
Plutonium is used in many war include Cold war.It is used in making bombs that’s deal heavy damage to mankind that’s why this is put on the top of the list of toxic elements.
