An atom s formal charge is the difference between the number of valence electrons in an isolated atom and the number of electrons assigned to that atom in a Lewis structure.
A PRECISE measure of the charge on an atom in a molecule is provided by calculating the number of electrons within a sphere of covalent radius using molecular wavefunctions. The results for alkyl substitution suggest that the simple qualitative ideas of the inductive effect may be less simple ...
Answer to: An atomic cation with a charge of +1 has the following electron configuration: (Ar) 4s^2 3d^{10} 4p^1. What is the chemical symbol for...
The important thing to understand about ions is that they are the only types of atom with anet charge. For convenience, chemists (and scientists in general in most cases) take the charge of an electron to be −1, while a proton has a charge of +1. ...

Ernest Rutherford showed that all of the positive charges in an atom are concentrated within a very small volume, called the nucleus, and was awarded the 1908 Nobel Prize in Chemistry for the work. The nucleus has dimensions on the order of 10−15 m! This requires some new thinking: if...
Among different advanced manufacturing approaches, 3D printing, as a novel fabrication technology, has great potential in producing optoelectronic devices. In the following sections, the recent progress of 3D printing of optoelectronic devices will be discussed. 3.1 3D printing of waveguide Waveguides ...
Electronegativity values are helpful in determining oxidation numbers in cases where it might otherwise be difficult to decide which atom has the positive and which the negative oxidation number. In binary covalent compounds and polyatomic ions such as PO43- or ClO4−, the more electronegative atom...
Adsorption energy (Ea) of an adsorbed atom is the energy, which has to be delivered to the adsorbed atom to be desorbed from the surface. From: Materials Surface Processing by Directed Energy Techniques, 2006 About this pageAdd to MendeleySet alert ...
