Why fluorine is the most reactive element?
Fluorine is the lightest halogen element and the most reactive chemical element. Because of its great propensity to attract electrons and the small size of its atoms, it has high chemical activity.
Why is F the symbol of fluorine?
Fluorine element is a given symbol based on its English name. The symbol of an element generally starts with the first letter of the element name. But we need to check elements with atomic numbers less than 9 whether any element is given symbol F or not.
Is fluorine used in toothpaste?
Most toothpastes now contain fluoride, and most people get their fluoride this way. Fluoride toothpaste is very effective in preventing tooth decay. The amount of fluoride in toothpaste is usually enough to reduce decay.
Is fluorine a real thing?
The most common fluorine minerals are fluorite, fluorspar and cryolite, but it is also rather widely distributed in other minerals. It is the 13th most common element in the Earth's crust. Fluorine is made by the electrolysis of a solution of potassium hydrogendifluoride (KHF2) in anhydrous hydrofluoric acid.

Fluorine is the thirteenth most abundant component in the Earth's crust. ... It is reactive in nature, storing fluorine is tough. ... There is just a single stable isotope of fluorine, F-19.
Which of these elements is a metal?
Examples of metal elements include iron, copper, silver, mercury, lead, aluminum, gold, platinum, zinc, nickel and tin.
Is sulfur a metal?
The non-metallic chemical element sulfur, 3216S , referred to in Genesis as brimstone and identified as element by Lavoisier, is the tenth most abundant element in the universe and the fifth most common element on Earth.
Which of the following element is a metal?
Calcium and potassium are metals and the other two are non-metals.
Is chlorine a metal?
Chlorine is the second halogen, being a nonmetal in group 17 of the periodic table. Its properties are thus similar to fluorine, bromine, and iodine, and are largely intermediate between those of the first two.
Who created the periodic table?
The creator of the periodic table, Dmitri Mendeleev, in 1869 began collecting and sorting known properties of elements, like he was playing a game, while traveling by train.
Can periodic table games be used for grade?
The periodic table game available on this page is for entertainment purposes only, and should not be used to grade students on their knowledge of chemical elements.
Does the Modern Periodic Table Change? If So, How and Who Does That?
The periodic table as we know it today is managed by the International Union of Pure and Applied Chemistry, or IUPAC (eye-you-pack).
What is the F block?
The f-block consists of two series lanthanides and actinides of the periodic table.
What is the modern periodic table?
The modern periodic table is the arrangement of all the known elements such that elements with similar characteristics are grouped. We know that the modern periodic table is made up of horizontal periods and vertical groups. In this article, we are going to study the similarities and periodicity of elements across the periodic table. We will study the different blocks: s-block, p-block, d-block, f-block and their characteristic properties, metals, metalloids, nonmetals, halogens, and noble gases.
What type of electron enters in a D block?
In d-block elements, a valence electron enters in d-orbital.
What is the electronic configuration of halogens?
The general electronic configuration of halogens is ns2np5.
Which elements of Group 1 and Group 2 belong to the S block?
The elements of Group 1 ( alkali metals) and Group 2 ( alkaline earth metals) which have ns1 and ns2 outermost electronic configuration belong to the s-Block Elements.
What are the shiny elements that form naturally below the surface of the Earth?
The lustrous or shiny elements that form naturally below the surface of the Earth are called Metals. These are elements having positive ions.
Why are noble gases called noble gases?
These gases are inert under normal conditions and that’s why they are called Noble gases.
What is the F block in a periodic table?
f block: bottom 2 rows separated from the rest of the Periodic Table
How many electrons are in the highest energy level?
The highest energy level (valence shell) contains 2 electrons, both electrons occupy an s subshell. The s subshell for this energy level (shell) is now full. The highest energy level (valence shell) of a Group 13 element already has 2 electrons in an s subshell, so the next electron occupies a p subshell to make 3 valence electrons in total ...
Where do group 1 and group 2 elements occur?
The highest energy level (valence shell) contains only 1 electron in an s subshell. Group 2 elements occur directly to the right of Group 1 elements.
How many electrons are in Group 18?
Group 18 elements have 2 s electro ns and 6 p electrons in their highest energy level (shell) which completes the s and p subshell. Transition metals are filling their d subshell with electrons, starting with Group 3 elements which have 1 electron in a d subshell.
What are the abbreviations for elements?
In fact, there are eleven of the abbreviations for the elements which don't seem to match the modern name. Those are subtle reminders of the history of the Periodic Table and the process of the discovery of elements over the millennia. Eight of these oddities are Au (gold), Ag (silver), Cu (copper), FE (iron), SN (tin), Pb (lead), Sb (antimony), and Hg (mercury): All were among the elements recognized by the ancient Greeks and Romans, and the abbreviations for those are based on a Latin or Greek term for the element.
Why do we use symbols in the periodic table?
It's easier to navigate the periodic table and write chemical equations and formulae once you know the symbols for the elements. However, sometimes it's easy to confuse symbols of elements with similar names. Other elements have symbols that don't seem to relate to their names at all! For these elements, the symbol usually refers to an older element name that isn't used anymore.
What does the word "K" mean in the word "potassium"?
Potassium was identified during the Middle Ages, and it's "K" is for kalium, a medieval Latin term for potash. W stands for tungsten because it was first identified in 1780 within the mineral known as wolframite, by French scientist Antoine Lavoisier (1743–1794).
