1.the smallest physical unit of an element or compound, consisting of one or more like atoms in an element and two or more different atoms in a compound. 2.a quantity of a substance, the weight of which is numerically equal to the molecular weight; gram molecule. ...
atom系一种element入面最细而且不能分割的部份,而Ion是由于atom/molecule得到或者失去electron时而令atom/molecule中的正负电荷失衡,得到净正或负电荷,咁ion都系element入面最细而且不能分割的部份?polyatomic ion系多过一个 atom 的 ion,咁他算不算系compound?
What is the Iupac name of this molecule? What is a triatomic molecule? What is the charge on the polyatomic ion hydrogen carbonate? What kind of compounds are named using prefixes? What is the name of the covalent compound PCl5? What is OH's chemical name?
theory and methods, tools for identifying the structure of gas-phase ions, what and what not to expect from gas-phase ions, ions containing C andpolyatomic ionscontaining one to three C atoms, ion structures, ions containing only carbon atoms, and those containing one, two or three carbon at...

Molecules that are composed of atoms of more than one type is called a polyatomic molecule. The molecular formula consists of chemical symbols for all the constituent atoms, where the number of atoms of each type is written as subscripts following their respective symbols....
Such reactive soft landing processes occur by ion/molecule reactions at the interface, although details of their mechanism and its timing have not been elucidated. The extent and nature of surface modification is controlled by choice of the total ion dose, the projectile ion and its energy. ...
In the present paper we describe the effect of the location of the ion source on the mass spectra obtained by multiphoton ionisation processes. Mass spectra measured with two different locations and sets of electrical parameters of the ion source are reported for the benzene molecule. Both sets ...
