Vanadium, Titanium, Molybdenum: Popular Alloying Metals

August 31, 2022

Vanadium was valued by Ford Motors in their manufacture of the legendary Model T. A tiny amount of it make a steel alloy much stronger, a property shared by molybdenum. Titanium dioxide has a high opacity when powdered, making it of value in the paint industry. […]

Technetium and Rhenium: The Early Transition Metals

August 30, 2022

Technetium provides corrosion resistance to steel. In addition, when cooled to 11° above absolute zero it also becomes a superconductor. It is this property that might one day expand its use so much so that its radioactivity might be tolerated. […]

The Unique Phase Properties of Mercury

August 21, 2022

Mercury’s low melting point could only be explained by the middle of the 20th century, as it was only around that time that physicists began using the theory of relativity with respect to the behavior of atoms. […]

The Diverse Properties and Trends of D-block Elements

August 21, 2022

The atomic radius, in d-block elements, tends to decrease gradually as we move from left to right. But as we move down, one has to take into consideration the f-subshell filling that occurs in period 6, prior to the d-subshell filling. […]

D-Block Elements and the Aufbau Order

August 21, 2022

There are five exceptions to the Aufbau filling order that one can predict using filled and half-filled subshells. The last one is with respect to platinum, which takes on a 6s1 4f14 5d9 configuration. […]
