Scandium 21 Sc

What element is 118 in real life

oganesson (Og), a transuranium element that occupies position 118 in the periodic table and is one of the noble gases.

Has element 119 been made

Ununennium, or element 119, is a predicted chemical element. Its symbol is Uue. Ununennium and Uue are substitute names made by the IUPAC, (meaning "one-one-nine-ium" in Latin) until permanent names are made. Ununennium is the element with the smallest atomic number that has not been created yet.

Is element 118 toxic

Oganesson is harmful due to its radioactivity. Characteristics: Oganesson is a synthetic radioactive metal and has only been produced in minute amounts.

What is the 119th elements

Ununennium, also known as eka-francium or element 119, is the hypothetical chemical element with symbol Uue and atomic number 119. Ununennium and Uue are the temporary systematic IUPAC name and symbol respectively, which are used until the element is discovered, confirmed, and a permanent name is decided upon.

Can there be elements beyond 118

It is unknown how far the periodic table might extend beyond the known 118 elements, as heavier elements are predicted to be increasingly unstable. Glenn T. Seaborg suggested that practically speaking, the end of the periodic table might come as early as around Z = 120 due to nuclear instability.

Can element 137 exist

Element 137 is Untriseptium (Uts), it is a hypothetical element and its name is temporary as it hasn't actually been discovered. The current name literally means 137. Many believe if ever discovered it will be named after the physicist Robert Feynman as he predicted the periodic table would end at element 137.

What is the rarest element in existence


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.

Does element 120 exist

Unbinilium, also known as eka-radium or element 120, is the hypothetical chemical element in the periodic table with symbol Ubn and atomic number 120.

Has element 123 been discovered

In real-life science, element 123 has yet to be discovered.

What’s the heaviest element


Oganesson has the highest atomic number and highest atomic mass of all known elements. The radioactive oganesson atom is very unstable, and since 2005, only five (possibly six) atoms of the isotope oganesson-294 have been detected.

What is the most unsafe element

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).

What is the 128th element

The element which comes on 128 number is Trititanium (Tt).

What is the 120th element

Unbinilium, also known as eka-radium or element 120, is the hypothetical chemical element in the periodic table with symbol Ubn and atomic number 120.

Has element 120 been found

No unbinilium atoms were identified. Neither element 119 nor element 120 was observed.

What are the 2 rarest elements

What is the strongest element


Impact strength determines how much energy a metal can absorb through impact without shattering or fracturing. Tungsten, which is Swedish for "heavy stone," is the strongest metal in the world. It was identified as a new element in 1781.

Is element 119 impossible

After 118, however, things stalled again. Fusion requires several milligrams of the target element, and producing enough einsteinium (element 99) to make element 119 is impossible with today's technology.

How was element 111 created

Roentgenium has no known biological role. A man-made element of which only a few atoms have ever been created. It is made by fusing nickel and bismuth atoms in a heavy ion accelerator.

What’s the hardest element

Can you name the hardest element It's an element that occurs naturally in pure form and has a hardness of 10 on the Mohs scale. Chances are you have seen it. The hardest pure element is carbon in the form of a diamond.

What element is toxic to humans

Trace elements that are most often associated with environmental toxicity are the heavy metals cadmium, chromium, cobalt, copper, iron, lead, mercury, nickel, silver, tin, and zinc, as well as the lighter elements aluminum, arsenic, and selenium.

Can elements be toxic

Some toxic, semi-metallic elements, including arsenic and selenium, are discussed in this page. In very small amounts, many of these metals are necessary to support life. However, in larger amounts, they become toxic. They may build up in biological systems and become a significant health hazard.

Does element 126 exist

Unbihexium, also known as element 126 or eka-plutonium, is the hypothetical chemical element with atomic number 126 and placeholder symbol Ubh.

What’s the 100th element

fermium (Fm), synthetic chemical element of the actinoid series of the periodic table, atomic number 100.

Does element 121 exist

Unbiunium, also known as eka-actinium or simply element 121, is the hypothetical chemical element with symbol Ubu and atomic number 121.
