Astronomers from the University of Turku in Finland and elsewhere have performed a broadband spectral and timing study of an ...

A new seaborgium isotope may unlock the path to discovering even shorter-lived superheavy nuclei through K-isomer states. An ...

The discovery and synthesis of new elements play a key role in the expansion of the periodic table. Between 2000 and 2016, ...

Look at the periodic table and find sodium (Na). The atomic number of sodium is listed as 11. This means sodium has 11 protons in its nucleus. Calculating Mass Number Example 1: Chlorine ...

Carolyn Krause presents the second part of the three-part series on the Oak Ridge National Laboratory 's role in the discovery of elements in the periodic table. Many of them have been synthesized ...

According to Jim Roberto, “nine elements have been discovered using ORNL isotopes. ORNL isotopes have been involved in the discovery of elements 61, 104, 105, 106, 114, 115, 116, 117 and 118.” ...

On February 7, 2016, the first National Periodic Table Day was founded on February 7, 2016. The day serves to promote the challenges overcome to develop the modern periodic table. Mr.

The classic Mendeleev periodic table sorts elements by number of electrons and then in groups that indicate how readily their atoms bond with others. That bondability factor is based on shell ...

It’s not every day an element gets added to the periodic table. The last time it happened was 2016, when four new elements became official. For these elements, reaching the table was an epic ...

He points out that theories suggest 172 elements can exist, which means that one-third of the table remains undiscovered. “For chemists, that’s incredibly exciting,” he says.

Some of the periodic table’s more familiar elements are already affected by special relativity. The theory explains why gold has a yellowish hue and why mercury is liquid at room temperature (SN ...
