What is the most used element?
HydrogenHydrogen is the most abundant element in the Universe; helium is second.
However, after this, the rank of abundance does not continue to correspond to the atomic number; oxygen has abundance rank 3, but atomic number 8.
All others are substantially less common..
What is the most dangerous chemical on Earth?
Botulinum toxin1. Botulinum toxin. Scientists differ about the relative toxicities of substances, but they seem to agree that botulinum toxin, produced by anaerobic bacteria, is the most toxic substance known. Its LD50 is tiny – at most 1 nanogram per kilogram can kill a human.
What is the strongest thing in the universe?
But it may be awhile before we figure out how to use what a new study suggests is the strongest material in the universe, known as “nuclear pasta” and it’s found in the crusts of neutron stars, reports Brandon Specktor at LiveScience.
What is the strangest element?
The most weird and wonderful elements in the periodic tableKrypton derives from the Greek ‘kryptos’, which means ‘hidden’.Antimony has been used for thousands of years and is even mentioned in the Qur’an.Its compound bismuth subsalicylate is also the main active ingredient in Pepto-Bismol – it probably tastes less like bubble gum in its elemental form, though.
What elements are toxic to the human body?
Conversely, there are a number of elements that are toxic to the human body, interfere with its functioning and undermine health—such as mercury, lead, cadmium, aluminum, and arsenic.
Which is stronger fire or water?
Water is stronger. Fire is easy to smother, needs fuel to keep going, has only one state of matter, and is on a smaller scale.
What is the strangest metal?
5 Metals with Very Strange Physical Properties#1 – Rhodium: More valuable than any other precious metal.#2 – Gallium: Beats like a living heart.#4 – Beryllium – Invisible to X-rays.#5 – Ruthenium – The Metal that Can Burn Forever.
What is the most deadly element to humans?

Which metal has the highest melting point?
tungstenOf all metals in pure form, tungsten has the highest melting point (3,422 °C, 6,192 °F), lowest vapor pressure (at temperatures above 1,650 °C, 3,000 °F), and the highest tensile strength.
What is the coolest looking element?
Liquid helium is literally the coolest element, forming only at -269 degrees Celsius. What’s cooler than cool? LIQUID HELIUM.
What are the 10 most important elements?
10 Most Useful Chemical ElementsKrypton. Krypton (Kr) isn’t just the element that makes Superman weak. … Curium. The element curium (Cm) is created by adding many helium ions to plutonium. … Lutetium. Lutetium (Lu) was discovered by Georges Urbain in 1907. … Zirconium (Zr) … Copper.
Which is the hardest metal on earth?
tungstenIn terms of tensile strength, tungsten is the strongest out of any natural metal (142,000 psi). But in terms of impact strength, tungsten is weak — it’s a brittle metal that’s known to shatter on impact. Titanium, on the other hand, has a tensile strength of 63,000 psi.

What is the most useful element?
SiliconSilicon is one of the most useful elements to mankind. Most is used to make alloys including aluminium-silicon and ferro-silicon (iron-silicon).
What is the most used element in the world?
HydrogenHydrogen is the commonest element in both the Universe (over 90%) and the Solar System (70.68%). Iron is the commonest element in the earth, accounting for 36% of the mass, whilst molecular nitrogen (N2) is the commonest in the atmosphere at 78.08% by volume or 75.52% by mass.
What burns a green flame?
A green flame, for instance, indicates the presence of copper. As copper heats up, it absorbs energy that’s manifested in the form of a green flame. A pink flame, on the other hand, indicates the presence of lithium chloride. And burning strontium chloride will create a red flame.
What Colour does gold burn?

What is the most expensive element in the world?
franciumThe most expensive natural element is francium. Although francium occurs naturally, it decays so quickly that it cannot be collected for use. Only a few atoms of francium have been produced commercially, so if you wanted to produce 100 grams of francium, you could expect to pay a few billion U.S. dollars for it.
What elements can’t be alone?
There are eight elements that form diatomic molecules, that cannot exist by themselves. They are high-lighted on the periodic table below. They are hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, iodine and astatine.
