Some asteroids are dense. So dense in fact, that they may contain heavy elements outside of the periodic table, according to a new study on mass density. The team of physicists from The University ...

This suggests that this rock, dubbed asteroid 33 Polyhymnia, may contain new elements that are not found on our periodic table. The space object is found in the Asteroid belt and measures around ...

Elements beyond the periodic table have been modeled, with physicists predicting their properties. The Arizona team did the same using the relativistic Thomas-Fermi model of the atom, attempting ...

Naturally occurring superheavy elements beyond those listed in the periodic table could potentially explain why asteroid 33 Polyhymnia is so dense, new research suggests.

The zigzag, staircase, line in the diagram of the periodic table above separates the metals, on the left, from non-metals, ... Density: low density – Li, Na and K are less dense than water: ...

At the far end of the periodic table is a realm where nothing is quite as it should be. The elements here, starting at atomic number 104 (rutherfordium), have never been found in nature. In fact ...

Give each student a copy of the periodic table of the elements, the periodic table of elements 1–20, and the activity sheet. Students will use the periodic table of elements 1–20, along with the ...

Aluminum is a metal in group IIIA of the periodic table with atomic number 13, an atomic weight of 26.982, and a density of 2.70. It has a melting temperature of 660 C. The electronic configuration of ...
