What element is atomic number 26?
iron
In February, we have selected iron, the most abundant element on Earth, with chemical symbol Fe (from the Latin word “ferrum”) and atomic number 26. A neutral iron atom contains 26 protons and 30 neutrons plus 26 electrons in four different shells around the nucleus.
What does the 26 in Fe mean?
Iron
Iron (Fe) is a grey metal that has the atomic number 26 in the periodic table. Iron’s symbol is Fe after the Latin ‘ferrum’ meaning iron.

Where on earth do you find most of the element with atomic number 26?
3History. The name derives from the Anglo-Saxon iron of unknown origin. The element has been known from prehistoric times. The symbol Fe is derived from the Latin ferrum for “firmness”.
What is the electron configuration for iron Fe element 26?
Electronic configuration of iron is [Ar] 3d6 4s2.
How did iron get on Earth?
Iron is made inside stars, specifically red super-giants. The elements form together inside a star during fusion. When the supernova occurs, the iron fragments are blasted into the space. This is how Iron came to Earth millions of years ago.

Iron/Electron configuration
What is the electron configuration for F 1?
Using standard notation, the electron configuration of fluorine is 1s22s22p5.
Who discovered fluorine 18?
The noble gases, or Group 18 (VIIIA), also known as the inert gases, generally do not react with other elements. Fluorine was discovered in 1886 by French chemist Henri Moissan (1852-1907). Moissan collected the gas by passing an electric current through one of its compounds, hydrogen fluoride (H 2 F 2 ).
What is Fe on the periodic table?
Fe. Iron. 55.847. Fe comes from the Latin name, ferrum. 36.
What is the electron configuration for iron Fe Element 26?
What is the purpose of atomic number 26?
atomic number 26 – a heavy ductile magnetic metallic element; is silver-white in pure form but readily rusts; used in construction and tools and armament; plays a role in the transport of oxygen by the blood.
What is the uncertainty of the NIST F1?
The uncertainty of NIST-F1 is continually improving. In 2000 the uncertainty was about 1 x 10 -15, but as of January 2013, the uncertainty has been reduced to about 3 x 10 -16, which means it would neither gain nor lose a second in more than 100 million years! The graph below shows how NIST-F1 compares to previous atomic clocks built by NIST.
Which is the 26th element in the periodic table?
iron is the 26th element in periodic table. 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.
Why is the NIST F1 called a fountain clock?
NIST-F1 is referred to as a fountain clock because it uses a fountain-like movement of atoms to measure frequency and time interval. First, a gas of cesium atoms is introduced into the clock’s vacuum chamber.
