The quantum mechanical approach is currently used to explain atomic structure. The study of fundamental constituents such as atoms, molecules, substances, metals, crystals, and other aggregates of the matter is where traditional chemistry begins. Let’s now see about some basic terms of chemistry ...
The number of protons in an atom is unique to each element. For example,carbonatoms have six protons,hydrogenatoms have one andoxygenatoms have eight. The number of protons in an atom is referred to as the atomic number of that element. The number of protons also determines the chemical be...
What is the molar mass of KMnO4? Molar Mass: Molar mass is the number of grams of a substance that equals one mole or6.02x1023molecules, also known as Avogadro's number. Molar mass can be used to convert between moles and grams, denoted byg/mol. ...
For their design, the team used a thin copper sheet between two pieces of also thin paper which has some flaps on it. It is the movement of these which generates a small amount of juice. Very small, but enough to power some medical devices and possible be a power source for nanobots,...
