Properties of Matter for Select Elements

By: Reneshia Williams

There are 118 different elements of the periodic table. The three most familiar elements under 80 as the atomic weight are Iron, Titanium, and Copper. The three most unfamiliar under 80 as the atomic weight are Yttrium, Vanadium, and Niobium.

Iron can also prevent Iron-deficiency anemia.

Iron is one of the most familiar. Its density is 7.874 g/cm3. And the melting/freezing point is 1538 °C. A fact on Iron is Iron derives its name from the Anglo-Saxon 'iren'. The element symbol, Fe, was shortened from the Latin word 'ferrum' meaning 'firmness'. And another is its history : Ancient Egyptian iron objects have been dated to around 3500 B.C. These objects also contain approximately 8% nickel showing the iron may have originally been part of a meteorite. The "Iron Age" began around 1500 B.C. when the Hittites of Asia Minor began to smelt iron ore and make iron tools.

Titanium is the 22nd element on the periodic table. Its density is 4.507 g/cm3. And the melting/freezing point of Titanium is 1668 °C.  Titanium hammers and Expensive pens are certain everyday uses with Titanium. Another cool fact about Titanium is that it was discovered by William Gregor 1791 (England).

Copper is the 29th element on the periodic table.It density is 8.92 g/cm3. The melting/freezing point of Copper is 1084.62 °C. 2 everyday uses of copper are in pennies and in some hair brushes. Two interesting facts on Copper are : Copper has been known since prehistoric time. It has been mined for more than 5000 years.

On the periodic table, Yttrium is the 39th element. Its density is 4.472 g/cm3. And the melting/freezing point is 1526 °C. A couple of everyday uses of Yttrium are In some lamps and a leftover metal finger.And an interesting fact on Yttrium is Yttria — earth containing yttrium — was discovered in Ytterby’s quarry by Johan Gadolin in 1794. In 1843, Carl Gustaf Mosander demonstrated that yttria could be resolved into the oxides (or earths) of three elements. Yttrium was the most basic one. The others were named erbia and terbia.

One of the most unfamiliar elements on the periodic table is Vanadium. This element has the density of 6.11 g/cm3. And the melting/freezing point is 1910 °C. And two interesting facts about on Vanadium are traces if it gives an emerald a green color and a few percent of Vanadium in steel creates hard, tough alloys, but the pure metal has few applictaions.

Niobium is the 41st element on the periodic table. The density of Niobium is 8.57 g/cm3. And the melting/freezing point is 2477 °C. And two interesting fact about this element is it can be used in earrings and tongue studs because it can be colored by oxidation.
