Periodic Table of Elements 1-10 By harrison flynn
What is the Periodic Table of Elements? The Periodic Table of elements is one of the most important chemistry references there is. It arranges all the known elements in an informative array. Elements are arranged left to right and top to bottom in order of increasing atomic number and atomic mass. Using the data in the table, scientists and students can find out things about one particular.
Helium is the 2nd element on the Periodic Table of Elements. Its symbol is HE and it's atomic number is 2. It has an atomic weight of 4.002602 meaning it is the second lightest element on the table. It was first detected as an unknown yellow spectral line signature in sunlight during a solar eclipse in 1868 by French astronomer Jules Janssen. Which gives it it's name Helium, after Helios ( the Greek god of the Sun).
Lithium is the third element on the Periodic Table of Elements, it is the third lightest of elements with an atomic weight of 6.938. It was first discovered in 1817 by Johan August Arfwedson when he discovered it in a Petalite ore. It’s atomic number is 3 and it’s symbol is Li.
Beryllium is the 4th element on the Periodic Table of Elements, it is the 4th lightest element with an atomic weight of 9.0121831. The mineral beryl which contains beryllium, has been used at least since the Ptolemaic Dynasty of Egypt. But was only called Beryllium in 1828. It’s symbol is BE and it’s atomic number is 4.
Boron is the 5th Element in the Periodic Table of Elements, it is the5th lightest element with an atomic weight of 10.806, it was first discovered inside borax giving it it’s name. Borax has been used since the 1600’s but boron has only been used since 1808. It’s symbol is B and it’s atomic number is 5.
Carbon is the 6th element on the Periodic Table of Elements. It is the 6th lightest element with an atomic weight of 12.0096. Carbon was discovered in prehistory and was known in the forms of soot and charcoal to the earliest human civilization 1722, René Antoine Ferchault de Réaumur demonstrated that iron was transformed into steel through the absorption of carbon. It’s atomic number is 6 and it’s symbol is C.
Nitrogen is the 7th element on the Periodic Table of Elements, it is the 7th lightest element with an atomic weight of weight 14.007. Nitrogen is formally considered to have been discovered by Scottish physician Daniel Rutherford in 1772, who called it noxious air. Though he did not recognize it as a new element. It's atomic number is 7 and it's symbol is N
Oxygen is the 8th element of the Periodic Table of Elements is the 7th lightest element with an atomic weight of 15.99903. It has been used forever but it was only produced in 1774, but they failed to recognize it as a distinct element. Although later on it was classified as an element. It’s symbol is O and it’s atomic number is 7.
Fluorine is the 9th element on the Periodic Table of Elements, it is the 9th lightest element with an atomic weight of 18.9984032. It became an element in 1886 when Henri Moissan finally managed to isolate elemental fluorine. People had been trying for 74 years to isolate elemental fluorine but could not do it as it was to dangerous. It's symbol is F and it's atomic number is 9.
Neon is the 10th element on the Periodic Table of Elements, it is the tenth lightest element with an atomic weight of, 20.1797. Neon was first discovered in 1898 by the British chemists Sir William Ramsay and Morris W. Travers. Neon was discovered when Ramsay chilled a sample of air until it became a liquid, then warmed the liquid and captured the gases as they boiled off. They found nitrogen, oxygen, and argon in it and also found a new element which they named it neon after the Greek word novum meaning "new". It's Atomic number is 10 and it's symbol is Ne.
