Among the 118 elements present in the periodic table, Plutonium is the most dangerous element which is harmful to human health and environment. It is dangerous owing to its toxicity, radioactivity and high reactivity. Plutonium is a heavy element with atomic number 94 and mass number 239 (actinide metal).
You can think of plutonium as the radioactive big brother to the other heavy metals. It's poisonous on its own, plus it floods its surrounds with alpha, beta, and gamma radiation. It's estimated that 500 grams of plutonium if inhaled or ingested, could kill 2 million people.
It's not illegal to own almost any element (plutonium and certain types of enriched uranium excepted), but there are very strict shipping restrictions for radioactive and otherwise potentially dangerous elements.
Astatine is a chemical element with the symbol At and atomic number 85. It is the rarest naturally occurring element in the Earth's crust, occurring only as the decay product of various heavier elements. All of astatine's isotopes are short-lived; the most stable is astatine-210, with a half-life of 8.1 hours.
Rhodium (Rh: atomic number 45)
It's the most expensive metal in the world. Rhodium is a rare metal element and highly valuable, even more so than gold. It's a silver-white metal with a reflective surface that doesn't corrode. Englishman William Wollaston discovered rhodium in 1803 in platinum ore from South America.
These elements cooperate together: wood creates fire, fire creates earth, earth creates metal, metal creates water, and water creates wood. And these elements fight together: wood destroys earth, metal destroys wood, fire destroys metal, water destroys fire, and earth destroys water.
This means that metal hinders (or defeats) wood, wood defeats earth, earth defeats water, water defeats fire, and fire defeats metal.
Hydroxides of s−block elements are strongest. Zn(OH)2 is the weakest base because it produces less number of OH−.
In short, the answer is no. The statement 'diamond is an element' is misleading as carbon itself is an element. While a diamond is composed of 100% of carbon with no other elements involved, it is not an element but simply an allotrope of the element carbon.
Steel is the second strongest and the most widely used metal in the world. It's an alloy of iron and carbon and contains small amounts of manganese, sulfur, oxygen phosphorus and silicon.
At sea level air pressure is actually stronger than water pressure.
Water is the opposing element of lightning.
Hydrogen and oxygen, on the other hand, cannot be decomposed into simpler substances. They are therefore the elementary, or simplest, chemical substances - elements. Each element is represented by a unique symbol. The notation for each element can be found on the periodic table of elements.
EARTH (Chinese: 土, pinyin: tǔ)
Represented by the colour yellow and a square shape, Earth's motion is patient, reliable, logical, governed by service and duty to others, militaristic, stubborn, very energetic.
However, despite the close-knit feel many families have in our community, blood isn't always thicker than water. A good friend says, “blood might be thicker, but sometimes water is there when blood isn't.”
The phrase “blood is thicker than water” is common in modern English. The popularly used phrase means that the bond you share with family is stronger than any other bond. It suggests you should be more committed to your family members than to friends, lovers, co-workers, etc.
In fact, as it spills out onto Earth's surface as lava, the runny rock's temperature is only a little lower than the hottest part of a candle flame: about 1200 °C. On the other hand, a big blob of lava contains many more bouncing particles than a small candle flame, so it has a lot more heat energy.
Fabrics made from glass, aramid, novoloid, sulfur, and saran fibers do not burn with a flame and can withstand high heat.
No. Fire can get hotter than Magma, it's not hotter by default. It's dependant on its fuel source.
Osmium, rhodium and iridium are probably the rarest metals found in the Earth's crust with average concentrations of 0.0001, 0.0002 and 0.0003 parts per million by weight respectively.
