Iron Iron is a chemical element with symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal in the first transition series. It is by mass the most common element on Earth, forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust.

- A necessary prerequisite to the construction of the periodic table was the discovery of the individual elements. Although elements such as gold, silver, tin, copper, lead and mercury have been known since antiquity, the first scientific discovery of an element occurred in 1649 when Hennig Brand discovered phosphorous.

Astronomy Chapter 19 Life In The Universe The modern-day organisms that seem oldest, in an evolutionary sense, are microbes that. live in the hot water around volcanic vents on the ocean floor. Nearly all of the oxygen in the Earth's atmosphere was originally produced by photosynthesis in the leaves of trees that covered the continents 3.5 billion years ago. The requirement of liquid water is the most severe constraint on the development of life.

The Earth is a little over 4.5 billion years old, its oldest materials being 4.3 billion-year-old zircon crystals. Its earliest times were geologically violent, and it suffered constant bombardment from meteorites.

History of Earth The first eon in Earth's history, the Hadean, begins with the Earth's formation and is followed by the Archean eon at 3.8 Ga. The oldest rocks found on Earth date to about 4.0 Ga, and the oldest detrital zircon crystals in rocks to about 4.4 Ga, soon after the formation of the Earth's crust and the Earth itself.

Antimony Antimony is a chemical element with symbol Sb (from Latin: stibium) and atomic number 51.ntimony has two stable isotopes: 121 Sb with a natural abundance of 57.36% and 123 Sb with a natural abundance of 42.64%. It also has 35 radioisotopes, of which the longest-lived is 125 Sb with a half-life of 2.75 years. In addition, 29 metastable states have been characterized.

Chemical element Ten materials familiar to various prehistoric cultures are now known to be chemical elements: Carbon, copper, gold, iron, lead, mercury, silver, sulfur, tin, and zinc. Three additional materials now accepted as elements, arsenic, antimony, and bismuth, were recognized as distinct substances prior to 1500 AD.

Oldest dated rocks The oldest dated rocks on Earth, as an aggregate of minerals that have not been subsequently broken down by erosion or melted, are more than 4 billion years old, formed during the Hadean Eon of Earth's geological history. Such rocks are exposed on the Earth's surface in very few places.

4.4 billion-year-old crystal is oldest piece of Earth This is the oldest and the best dated of all the crystals that have been reported, said John Valley, lead study author and professor in the Department of Geoscience at the University of Wisconsin-Madison. This crystal is a translucent red, Valley said, but glows blue when bombarded with electrons.

Oldest rocks on Earth found The oldest zircons, from grains in Western Australia, are about 4.36 billion years old. The Nuvvuagittuq rocks are the oldest whole rocks found so far though, said geologist Richard Carlson of the Carnegie Institution, who analyzed the rocks with Jonathan O'Neil, a Ph.D. student at McGill University in Montreal. The team's findings are detailed in the Sept. 25 issue of the journal Science.

List of elements by stability of isotopes Of the first 82 elements in the periodic table, 80 have isotopes considered to be stable. The 83rd element, bismuth, was traditionally regarded as having the heaviest stable isotope, bismuth-209, but in 2003 researchers in Orsay, France, measured the half-life of 209 Bi to be 7026599594400000000♠1.9×1019 years. Technetium, promethium and all the elements with an atomic number over 82 only have isotopes that are known to decompose through radioactive decay. No undiscovered elements are ...

- There are 80 elements that have at least one stable isotope and 38 that have exclusively radioactive isotopes, which decay over time into other elements. Iron is the most abundant element (by mass) making up the Earth, while oxygen is the most common element in the crust of the earth.he standard state, also known as reference state, of an element is defined as its thermodynamically most stable state at 1 bar at a given temperature (typically at 298.15 K). In thermochemistry, an element is defined to have an enthalpy of formation of zero in its standard state.

Timeline of chemical element discoveries The earliest known use of charcoal was for the reduction of copper, zinc, and tin ores in the manufacture of bronze, by the Egyptians and Sumerians. Diamonds were probably known as early as 2500 BCE. The first true chemical analyses were made in the 18th century, and in 1789 carbon was listed by Antoine Lavoisier as an element.
