What Element Is The Most Useful?

What element is the most useful?

Silicon

is one of the most useful elements to mankind. Most is used to make alloys including aluminium-silicon and ferro-silicon (iron-silicon).

What element has no uses?

Nobelium

has no uses outside research. Nobelium has no known biological role. It is toxic due to its radioactivity. Nobelium is made by bombarding curium with carbon in a device called a cyclotron.

Is there an element with no use?

A few elements have no current uses, such as

protactinium and berkelium

. The short-lived, man-made elements starting with einsteinium have no uses at the moment either, as they don’t stick around long enough for scientists to experiment on them.

What is the least useful metal?

Protactinium

. While francium is the rarest unstable metal, protactinium is the rarest stable metal. There’s one thing that the two metals have in common; they both don’t have any practical uses!

Is oxygen the most important element?

Oxygen is an important element that is needed by most life forms on Earth to survive

. It is the third most abundant element in the universe and the most abundant element in the human body. Oxygen has 8 electrons and 8 protons. It is located at the top of column 16 in the periodic table.

Carbon is the only element that can form so many different compounds because

each carbon atom can form four chemical bonds to other atoms

, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules.

In other words, water is weak against earth but strong against fire. Fire is weak against water and strong against wind, which is strong against lightning.

Earth is strong against water but weak to lightning

. When two elemental jutsu are used against each other, the weaker element does 25% less damage.

That’s about the same amount of energy in 10 trillion trillion billion megaton bombs! These explosions generate beams of high-energy radiation, called

gamma-ray bursts (GRBs)

, which are considered by astronomers to be the most powerful thing in the universe.

Within the standard 92 elements found in nature, most have at least some practical use, the most useless probably being

Thulium

, which is usually the butt of jokes on the subject, but still has some actual applications (http://en.wikipedia.org/wiki/Thulium#Applications).

Plutonium

. Pretty much all of the radioactive elements are cool. Plutonium is particularly awesome because it truly does glow in the dark. Plutonium’s glow isn’t due to its radioactivity, though.

Some elements, like

lithium and nickel

, can be used to make many types of batteries. Others like, vanadium and cadmium, are, as of today, only used in one type of battery each.

protactinium (Pa)

, radioactive chemical element of the actinoid series of the periodic table, rarer than radium; its atomic number is 91. It occurs in all uranium ores to the extent of 0.34 part per million of uranium. Its existence was predicted by Russian chemist Dmitry Mendeleyev in his 1871 periodic table.

And so we are left with

carbon

, the most versatile, most adaptable, most useful element of all. Carbon is the element of life.

Is fire matter? Matter is anything that has mass and occupies space.

The flame itself is a mixture of gases (vaporized fuel, oxygen, carbon dioxide, carbon monoxide, water vapor, and many other things) and so is matter

. The light produced by the flame is energy, not matter.

Oxygen is not flammable, but it can cause other materials that burn to ignite more easily and to burn far more rapidly

. The result is that a fire involving oxygen can appear explosive-like.

Hydrogen is the most abundant element in the universe, but not on Earth due to its light weight, which allows the gas to just float off into space. Hydrogen is essential to our life –

it fuels the sun, which converts hundreds of million tons of hydrogen into helium every second

.

The quick answer is:

Diamond is a pure element

, carbon; gold is a pure element, gold; and rust is a compound, Iron Oxide, of iron and Oxygen. Diamond is pure elemental carbon, compressed to its crystal form, under extreme heat and pressure deep within the Earth.

Between -10% and -20% C the tensile strength of ice is generally between 0.7 and 3.1 MPa (pascals are a measure of pressure). The flame of a fire is composed of hot gas which if hot enough may be ionized to plasma. It has a tensile strength of 0. In conclusion

ice is stronger than flame
