internationalOn 28 November 2016, the International Union of Pure and Applied Chemistry (IUPAC) approved the name and symbols for four elements: nihonium (Nh), moscovium (Mc), tennessine (Ts), and oganesson (Og), for element 113, 115, 117, and 118, respectively....
Iupac invited the teams to propose names for the new elements,confirming the suggested names in June this year. According to the Iupac guidelines, an element can only be named after a mythological concept or character, a mineral, a place or geographical region, an elemental property or a scien...
To determine the IUPAC name of the element with atomic number 108, we can follow these steps:1. Identify the Atomic Number: The atomic number given is 108.2. Break Down the Atomic Number: We will break d
115 and 117, but these elements haven't been discovered, much like Mendeleyev left gaps in his table for elements that hadn't turned up yet. Of course, nothing in science is static, so it's always good to check with IUPAC if you're unsure about whether an element is official or not...

An interval in square brackets provides the lower and upper bounds of the standard atomic weight for that element. No values are listed for elements which lack isotopes with a characteristic isotopic abundance in natural terrestrial samples. See PAC for more details. InternatIonal UnIon of PUre and...
In the absence of parentheses, the uncertainty is one in that last digit. An interval in square brackets provides the lower and upper bounds of the standard atomic weight for that element. No values are listed for elements which lack isotopes with a characteristic isotopic abundance in natural ...
1.1 Atomic weight of an element The atomic mass, ma, of an unbound neutral atom of carbon-12, ma(12C), in its nuclear and electronic ground states is 12 Da exactly, where Da is the symbol for unified atomic mass unit, and alternative symbol is u. The atomic weight (also called the ...

Element 113 is the first element to have been discovered in an Asian country. For the element with atomic number 115, the name proposed is moscovium with the symbol Mc and for element with atomic number 117, the name proposed is tennessine with the symbol Ts. These are in line with ...
