Fluorine (F), most reactive chemical element and the lightest member of the halogen elements, or Group 17 (Group VIIa) of the periodic table.

The name derives from the Latin fluere for “flow” or “flux” because fluorite (CaF2) was used as a flux in metallurgy owing to its low melting point….Fluorine.

Chemistry Portal A period 6 element is one of the chemical elements in the sixth row (or period) of the periodic table of the elements, including the lanthanides.

Grouped elements behave chemically in similar ways. from being too wide. Lanthanides are atomic numbers 57–70. Actinides are atomic numbers 89–102.

In the sixth period (n = 6) of the periodic table, 6s, 4f, 5d and 6p orbitals are filled in the increasing order of the energy. Total 16 orbitals are available each of which contains a maximum 2 electrons. Thus, the sixth period can accommodate maximum 32 elements.

The reason why Lanthanides and Actinides are located at the bottom of the periodical table is because of their properties and in the block in which electrons fill up. The lanthanides include elements 58 to 71 (fill out the 4f subshell) and the actinides include elements 89 to 103 (fill out the 5f subshell).

They are named after the first element in the series, actinium. The actinides group includes mostly man-made elements with only a few exceptions such as uranium and thorium. The actinides are most known for the elements uranium and plutonium which are used in nuclear reactors and nuclear bombs.

Nitrogen – 2.4kg The four most abundant elements in the human body – hydrogen, oxygen, carbon and nitrogen – account for more than 99 per cent of the atoms inside you. They are found throughout your body, mostly as water but also as components of biomolecules such as proteins, fats, DNA and carbohydrates.

The actual point of human body containing Gold has recently been determined. It plays a vital role in health and maintenance of the joints. Also, being a good conductor of electricity, it actually helps in transmitting electrical signals throughout the body.

– Hydrogen is found in sugar, proteins, starch and fats which are important part of human diet. – Hydrogen is an important component of water. Because of water, cells of the body remains hydrated and help in removing toxins from the body.

Carbon is the most important element to life. Without this element, life as we know it would not exist. As you will see, carbon is the central element in compounds necessary for life.

• Oxygen.
• Hydrogen.
• Helium.
• iron.
• sodium.
• titanium.
• nitrogen.
• chlorine.

Many elements make up the human body, but only three occur in abundance. These elements, oxygen, carbon, and hydrogen, combine to form the constituents of some of the most essential processes in the human body, such as cellular respiration.

Oganesson is a synthetic chemical element with symbol Og and atomic number 118. It was first synthesized in 2002 at the Joint Institute for Nuclear Research (JINR) in Dubna, near Moscow in Russia, by a joint team of Russian and American scientists. Oganesson is believed to exist in form of solid.

Though sandwiched between two very practical elements on the periodic table — thorium and uranium — protactinium is pretty much useless. The dearth of applications can primarily be attributed to the element’s rarity — it’s present at only a few parts per trillion in Earth’s crust.

Within the standard 92 elements found in nature, most have at least some practical use, the most useless probably being Thulium, which is usually the butt of jokes on the subject, but still has some actual applications (http://en.wikipedia.org/wiki/Thulium#Applications).
