discoveries. Plastic has shaped the modern revolution by allowing humans to have a cheap alternative to otherwise much more expensive materials. Plastic allows people to produce products in very large masses, while keeping the cost very low. The elements in plastic can be traced back to the supernovae of stars, but plastic was only able to become create the adaptable and affordable material it is today through the building upon of information over generations, in a process called collective learning

Strontium is a chemical element with symbol Sr and atomic number (protons in nucleus) 38 and atomic weight 88.1 It is a soft, silver-gray metal, and has physical and chemical properties like to Calcium and Barium. It is available as four stable isotopes ubiquitously (Isotopes are differ in forms of an by number of protons in nucleus but possess a variable number of neutrons.) Strontium-88 is the most dominant among other forms, comprising 83% of natural strontium, where in additional three stable

perfectly symmetrical either. The form resolves itself via a reinterpretation of the central, key section. That thematic section starts the piece, but it does not end the piece. The coda is a completely different phrase from the main theme, but in its key tonic element. The opening eight bars can be considered the central phrase and theme, if not the "chorus" of the string quartet. This thematic element anchors the ear and provides a foundation and structure for the entire composition. The opening

there are elements that are vital for both humans and plants. This indispensable and nourishing element that both humans and plants need is magnesium. Magnesium is the eighth most abundant element in the Earth’s crust and the fourth most abundant element in the human body. This particular element plays an imperative role in the human wellbeing. This essential element is the earth’s natural human health fix. Incipiently, magnesium derives as an alkaline earth metal that is the second element

discover me was in England. My element symbol is Ca. The representative groups and family I belong in is 2, Alkaline and also the symbols of the other family members is Be, Mg, Ca, Sr, Ba, and Ra. I have 24 isotopes however, the most stable isotopes in calcium is Ca 42, Ca 44, Ca 46, and Ca 48. The type of element I am is a metal because calcium is a chemical. The state of

I do not conduct electricity and I don’t bond well with other elements. Who am I? 5. I’m the main element found in steel. Who am I? 6. I’ve got the 2nd highest number of protons in my group. Who am I? 7. I am known to form up to 10 million different compounds. Who am I? 8. I was denied as an element at first because I didn’t fit in Dmitri's’

spontaneous decay, a new element, known as the daughter element, is formed with different properties from the original or parent substance. In addition to this formation, alpha and beta particles are emitted from the nucleus of the parental compound. Respectively, Rutherford and Soddy each received a Noble prize in the field of nuclear chemistry due to their outstanding scientific findings. In 1908, Rutherford was awarded the Noble prize for his investigations concerning the decay of elements and the chemistry

From discovering elements, to the creation of the periodic table, to determining new trends, scientists continue to build upon and enhance existing knowledge of the basic components of chemistry. Chemists, as well as many other researchers, rely heavily on the periodic table of elements and its many properties that are widely accepted and believed to hold true. These elements are arranged on the periodic table according to their atomic number or the number of protons in the nucleus. How the properties

How can one human mind organize and memorize over 100 elements? In 1869, Dmitri Mendeleev, a Russian chemist and inventor, was credited with creating and publishing the Periodic table. The Periodic table is an arrangement of the chemical elements discovered on earth. These elements are organized by their atomic number and similarities between chemical properties. The Periodic table holds 118 elements which can be broken down into smaller classifications, groups (vertical), periods (horizontal) and
