The periodic table’s arrangement also allows scientists to discern trends in element properties, including electronegativity, ionization energy, and atomic radius. Many scientists worked on the ...

It melts at 1410 C. The electronic configuration of the silicon atom is: (Ne)(3s) 2 (3p) 2, and the atomic radius is 0.132 nm. Silicon has the diamond cubic crystal structure with a lattice parameter ...

For comparison, the radius of a typical bacterium is 1 × 10-6 m and the radius of a human hair is about 1 × 10-4 m.

The electronic configuration of magnesium is (Ne)(3s) 2, and the atomic radius is 0.16 nm. Magnesium has an hcp lattice with a = 0.321nm and c = 0.521 nm. The diagram shows a schematic unit cell.
