What is the crystal structure of graphene? What atomic particle in an atom is the same for each element? Which particle of an atom has the least mass? Carbon has different isotopes. What is different between an atom of 12c and an atom of 13c?
The backbone structure of silicone oils is made up of a chain of alternating silicon and oxygen atoms. Each silicon atom is bonded to two carbon-based substitution groups, almost invariably methyl groups. Within the silicone oils themselves, the chains glide and slip over one another, so the ...
Methylation is a simple biochemical process. It is the transfer of four atoms – one carbon atom and three hydrogen atoms (CH3) – from one substance to another. The addition of methyl groups can affect how some molecules act in the body. What is methylation in the body? When optimal meth...
In philosophy, essence is considered the attribute or set of attributes that make an entity or substance what it fundamentally is. Whereas, in science, an element is a substance entirely made of one type of atom. 10 The essence of a concept or thing often remains abstract and philosophical,...
(Mathematics) Of, relating to, or being a prime number. Primary (of an organic compound) having its functional group located on a carbon atom which is bonded to no more than one other carbon atom A primary alcohol Prime The period of greatest physical and mental robustness Athletes in the ...
Hydrogen atom- A simple electric dipole (Photo Credit : general-fmv/ Shutterstock) Amagnetic dipoleis quite similar to an electric dipole, except that it’s composed of magnetic charges. A simple bar magnet is the best example of a magnetic dipole. One end of the bar constitutes the north...
The Physics of a Semiconductor There are some materials, which have neither good conductivity nor bad conductivity of electricity. They have a moderate range of electrical conductivity. The examples of such materials are germanium, silicon, carbon etc. A
, the three oxygen atoms that compose that molecule are bonded in a unique way. Two of the oxygen atoms are bonded by a double covalent bond (two pairs of electrons being shared), and one of those oxygen atoms is simultaneously sharing a coordinate covalent bond with a third oxygen atom....
They appear to be part of an investment scam, run out of Germany by someone named Ingo Wolf and a close circle of friends. They’ve been claiming that ordinary, everyday osmium (the kind your aunt keeps in her kitchen drawer, presumably) is highly dangerous and that only theirs, rendered...
(O2) using electricity. This process, called water electrolysis, is a promising option for carbon-free hydrogen production since the electricity can be sourced from nuclear or renewable energy, such as wind and solar. Scientists and engineers are working to improve and lower the cost of hydrogen...
