However, for example, silver can form an ion with +1 charge, whereas zinc and cadmium can gain a +2 charge. To find out whether an atom in these groups form ions more generally and determine their charges, the best thing to do is directly look up the element you're interested in. R...
Charge-Exchange Excitation and cw Oscillation in the Zinc-Ion Laser dominant mechanism for excitation of these lines is thermal-energy charge-transfer collisions between zinc atoms and both atomic and molecular ions of helium... RC Jensen,GJ Collins,WR Bennett - 《Physical Review Letters》 被引量...
Zinc AtomWe have studied the distribution of Born effective atomic charge amplitudes over orbitals in cubic ZnX semiconductors, analyzed the projected electronic densities of states for the zinc and chalcogen s, p, and d states, and examined zinc and chalcogen orbital hybridization effects. Covalence...
The great number of α particles which are projected from radium is weil illustrated by the multitude of scintillations observed when the α particles from a trace of radium fall on a screen of zinc sulphide. We shall see later that 136 million α particles are expelled every second from one...
The method was tested to describe the structure of a variety of zinc complexes where the structures are known from X-ray investigations. For small molecules, ab initio data were used as references. For the larger complexes, data from semi-empirical calculations were compared with the force field...
What is the composition of the nuclear of an atom and what charge are the nuclei? Nucleus The nucleus of an atom is the small, dense region in which the neutrons and protons are located. The nucleus is the center of an atom with the electrons revolving around the nuc...

On the periodic table of elements, transition metals are elements with partially filled d orbitals, or that have the ability to form partially filled d orbitals. An orbital is a location in an atom where we'll most likely find an electron (a negatively charged subatomic particle); they ...
–He makes the cathode plate porous and applies a layer of zinc sulphide on it. –Later, A high voltage current of about 10kv was allowed to pass through the tube. –When the atmospheric pressure was gradually decreased below 1 atm a gas illumination was seen at the back of the cathode ...
The atom types for most carbon atoms in ZINC000001644610 should be C.ar, representing aromatic carbons. The compound is correctly aromatized in the generated pdbqt file, probably because the bond section specifies the aromaticity of the bonds. The atom types for the phenolate oxygens should be...
