An element is a substance that cannot be broken down to simpler substances by chemical means. Elements are the substances that are listed in the periodic table and are the building blocks for everything on earth. Each element has a unique atomic number. The atomic number...
c. carbon d. water Periodic Table: The periodic table is an organized list of the elements that are found in the universe. These elements are organized into rows and columns by using patterns seen on valence shells, and chemical properties that make them unique. Answer...
Fig. 1: Concept, design and properties of the piezo-ionic-electric electronics. Working mechanism As mentioned previously, we are delighted to find that the PNP electronics does not require additional corona-polarization after preparation to activate piezoelectric response as before. What replaces such...

Basic amino acids have R-groups that contain positively charged functional groups, which can form ionic bonds with negatively charged groups. Examples include lysine (Lys), arginine (Arg), and histidine (His). Often charged side chains appear at the protein surface to enable solubility in water....
carbon-based structural units, substituents, functional groups, heterocyclic structures and functional compounds. The combination and arrangement of these molecular structural units determine the properties and functions of the compounds. ChemScene has been committed to the design and development of high-end...

While bond strengths have been theoretically computed accurately and experimentally determined, the number of bonds is a more contentious issue, especially for complicated multi-reference systems like C2. We have developed an experimentally verifiable approach to determine bond numbers from excited spin ...
Molecules can be attracted to one another due to different forces that are applicable to the molecule. The interaction is referred to as the intermolecular forces of attractions. There are different types of intermolecular forces of attractions and it all ca...
