all of the following were true of the center of the atom EXCEPT that it (A) had not yet been seen by the naked eye(B) contained elements that were positively charged(C) was very little larger than a molecule(D) followed experimentally determinable processes(E) was smaller than 1/125 ...
A molecule is defined as the smallest unit of a compound that contains the chemical properties of the compound. Molecules are made up of groups of atoms. Describing the structure of an atom, an atom is also sub-divided into smaller units. Protons, electrons, and neutrons are sub-particles ...
The molecule H@C20H19 containing one stable carbon atom with all four single bonds directed toward the same side of the nucleus is reported here. Its geometry, electronic properties, vibrational frequencies and heat of formation have been calculated at the B3LYP/6-311+G(d,p) level of theory...

The theory of the superradiance18,33,34,35 predicts a reduction in the collective radiative decay and consequently an improvement in quality factor (Q-factor) by reducing the number of two-level emitters confined in a spatial region comparable or smaller than the wavelength. This has also been ...
