A chemical element, or an element, is defined as a material which cannot be broken down or changed into another substanceusing chemical means.Elements may be thought of as the basic chemical building blocks of matter. There are 118known elements. Each element is identified according to the numb...
Fermium-257 is the heaviest isotope that is obtained via neutron capture, and can only be produced in picogram quantities. What makes Nihonium a unique element? Nihonium is a synthetic chemical element with the symbol Nh and atomic number 113. It is extremely radioactive; its most stable known...
No exact definition of an “organic” substance has been agreed upon by the chemical community and textbook definitions vary substantially. The question of what exactly constitutes an “organic” substance is explored in this paper. Various carbon-containing substances that have been by some considered...

This material has the typical heat resistance and chemical properties of para-aramid. Step 2: Continuous filament yarn spinning Next, the polymer is dissolved in sulfuric acid to create a liquid crystalline solution. The solution is then spun into fine, naturally yellow or dye-infused continuous...
Poly(acrylic acid) or PAA (CAS number 9003-1-04) is a type of polymer. The monomer of poly(acrylic acid) is Acrylic Acid. In a water solution at neutral pH, many of the side chains of PAA will lose their protons and acquire a negative charge. For a description of unrelated compounds...
It may come as a surprise, but silicon and silicone are two very different things. In short, silicon is a naturally occurring chemical element, whereas silicone is a synthetic substance. Silicon is the 14th element on the periodic table. It's a metalloid, meaning it has properties of both ...
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, ...
Speaking of vulcanizing agent, we usually think of it as a chemical element but we may not know it well. The vulcanizing agent can make the rubber molecular chain react and make the linear molecules form a three-dimensional network structure. So what are the effects of vulcanizing agents?1....
Organic chemistry is the study of the chemical reactions and molecules that contain carbon. Carbon is an important molecule in chemistry because it can make four bonds and is a major element of living things. Answer and Explanation:1 Resonance occurs when there are multiple valid configurations for...
