How WEll Do You Know Your Elements? What are their roles ?
By-Jose HERRERA
It is important for you to know how well everything is set up. It's up to you to understand what each element, but before we get started take a quiz. See how well can you do and notice interesting things that may shook you.

So before mentioning the elements and what are their capabilities. I would like to mention where did the periodic table come from. Did you know that Dmitri Mendeleev was the inventor of the periodic table? He was a Russian chemist and inventor; He created his own version of the periodic table of elements. Now going back to the periodic table, such table was arranged based on the chemical elements. It's organized by their atomic numbers, electron configuration, and recurring chemical properties. It consists of groups and periods.
The standard form of the table includes periods (usually horizontal in the periodic table) and groups (usually vertical). Elements in groups have some similar properties to each other. There is no one single or best structure for the periodic table but by whatever consensus there is, the form used here is very useful. The periodic table is a masterpiece of organized chemical information. The evolution of chemistry's periodic table into the current form is an astonishing achievement with major contributions from many famous chemists and other eminent scientists.
Now that you have been able to take the quiz and get a background on how elements were arranged, Learn interesting facts about various elements.
Calcium is one of the elements you need in order to live, so it's worth knowing a little bit about it.
Element 117 was discovered?
On 1 May 2014 a paper published by J. Khuyagbaatar and others states the superheavy element with atomic number Z = 117 (ununseptium) was produced as an evaporation residue in the 48Ca and 249Bk fusion reaction at the gas-filled recoil separator TASCA at GSI Darmstadt, Germany. The radioactive decay of evaporation residues and their α-decay products was studied using a detection setup that allows measurement of decays of single atomic nuclei with very short half-lives . Two decay chains comprising seven α-decays and a spontaneous fission each were identified and assigned to the isotope 294Uus (element 117) and its decay products.
This reinforces a paper published on the 5th of April, 2010 and others claim the synthesis of a new element with atomic number 117. The discovery of a new chemical element with atomic number Z=117 is reported. The isotopes 293117 and 294117 were produced in fusion reactions between 48Ca and 249Bk. Decay chains involving eleven new nuclei were identified by means of the Dubna Gas Filled Recoil Separator. The measured decay properties show a strong rise of stability for heavier isotopes with Z>=111, validating the concept of the long sought island of enhanced stability for super-heavy nuclei."
Element 117 is an atom with 117 protons in its nucleus, it was previously one of the missing items on the periodic table of elements. These super-heavy elements, which include all the elements beyond atomic number 104, are not found naturally on Earth, and thus have to be created synthetically within a laboratory.
In addition to the previous important facts, here are some other influential aspects to know:
Lastly, after all these facts have been presented, if you are still interested in knowing more about such impacting elements that affect our daily lives; visit these websites. Enjoy! And remember that Chemistry is fun

Calcium is one of the elements you need in order to live, so it's worth knowing a little bit about it.
- Calcium isn't found free in nature, but it can be purified into a soft silvery-white alkaline earth metal.
- Calcium is the 5th most abundant element in the Earth's crust, present at a level of about 3% in the oceans and soil.
- The element is essential for animal and plant nutrition.

In addition to the previous important facts, here are some other influential aspects to know:
- Hydrogen is highly flammable and is the most common element found in our universe.
- Liquid nitrogen boils at 77 kelvin (−196 °C, −321 °F).
- Around 1% of the sun’s mass is Oxygen.
- Helium is lighter than the air around us so it floats, that's why it is perfect for the balloons you get at parties.
- Carbon comes in a number of different forms (allotropes), these include diamond, graphite and impure forms such as coal.
- Under normal conditions, oil and water do not mix. More oil facts.
- Although it is still debated, it is largely recognized that the word 'chemistry' comes from an Egyptian word meaning 'earth'.
- The use of various forms of chemistry is believed to go back as long ago as the Ancient Egyptians. By 1000 BC civilizations were using more complex forms of chemistry such as using plants for medicine, extracting metal from ores, fermenting wine and making cosmetics.
- Things invisible to the human eye can often be seen under UV light, which comes in handy for both scientists and detectives.
- Humans breathe out carbon dioxide (CO2). Using energy from sunlight, plants convert carbon dioxide into food during a process called photosynthesis.
- Chemical reactions occur all the time, including through everyday activities such as cooking. Try adding an acid such as vinegar to a base such as baking soda and see what happens!
- Above 4 °C, water expands when heated and contracts when cooled. But between 4 °C and 0 °C it does the opposite, contracting when heated and expanding when cooled. Stronger hydrogen and oxygen bonds are formed as the water crystallizes into ice. By the time it's frozen it takes up around 9% more space.
