How are elements classified in the periodic table? How does the number of atoms change during a chemical reaction? How many naturally occurring elements are there? What are the types of chemical reactions? What is formed when two or more atoms join together chemically?
At present, 118 elements are known to us. All these have different properties. Out of these 118, only 94 are naturally occurring.
The global problem of the presence of human and veterinary pharmaceuticals in the environment is under investigation. Despite the increase in the knowledge of its sources, fates and impacts, the assessment of risks and the derived prevention actions are limited to single cases. The predicted increasi...
Many of today's electronic devices require magnets to function. This reliance on magnets is relatively recent, primarily because most modern devices require magnets that are stronger than the ones found in nature. Lodestone, a form of magnetite, is the strongest naturally occurring magnet. It can...
Leptin, a protein occurring naturally in the blood, appears to regulate how much fat the body carries by speeding up the metabolism and decreasing the appetite when the body has too much fat. Mice that do not naturally produce leptin have more fat than other mice, but lose fat rapidly when...
Prion-like low-complexity domains (PLCDs) have distinctive sequence grammars that determine their driving forces for phase separation. Here we uncover the physicochemical underpinnings of how evolutionarily conserved compositional biases influence the ph

The AMU difference occurs because U-238, which is the most abundant naturally occurring uranium isotope, has three more neutrons in its atom than U-235. U-235 is used in nuclear reactors to generate nuclear energy by the process ofnuclear fission. It is also one of the key ingredients of...
