about the nature of the molecule. After forming, ions get electrostatically directed into the analyser of mass spectrometer and they get separated according to their mass to charge ratios. It is very important to know the condition of the observed ions if positively or negatively charged. Molecular mass is provided by the results of molecular ionization which renovates gas phase samples into ions, ion separation or mass analyser that categories the ions using their masses through electromagnetic fields

1.1 Ion Implantation Ion implantation is a materials engineering operation where ions of a material are accelerated in an electric field and impacted into a solid. Ion implantation can also be referred to as a technique used to deposit precise quantities of n-type and p-type dopants or impurities into a semiconductor at a low temperature. Ion implantation alters the physical, chemical, electronic properties of a material by forcibly impacting different types of ions into the material. In ion implantation

The Separation and Identification of a Series of Cations Ethan Northcutt BB2 November 2nd, 2016 Abstract Ten cations were reacted with eleven anions and the results of the reactions were recorded; the reactions were performed so that the results could be used in the qualitative analysis of an unknown mixture containing a combination of the same ten cations. There are some distinct differences between the reactions that occurred and the reactions that were predicted to occur. The discrepancies

used by analytical chemist for the creation of ions from a sample. The technique uses electricity to form an exceptionally fine liquid aerosol. Other techniques that were used before electrospray used gas to form these aerosols for analyses. Electrospray is particularly useful over using gas because it is a soft ionization technique. Soft ionization techniques ionize the sample with minor fragmentation of the molecule, giving an observable molecular ion for the mass spectrometer to measure. This is

When analyzing a blood sample containing drugs, often a normal scale or balance cannot detect the mass of the drugs in the sample due to the small size of the sample. In that case, in order to properly determine the mass of a drug in a sample, it becomes necessary to utilize a mass spectrometer. A mass spectrometer can measure the mass of atomic-sized particles with great accuracy (Jeol, 2006). In forensic toxicology, mass spectrometry can provide scientists with the identity and quantity of a drug

between aqueous iron ions (Fe3+) and aqueous thiocyanate ions (SCN-) reacting to form aqueous FeSCN2+ was observed.2 Since this process is an equilibrium reaction, it can also proceed in the reverse direction where FeSCN2+ decomposes to form Fe3+ and SCN-. One of the initial starting reactants for this experiment was Fe(NO3)3, which decomposes to form iron ions and nitrate ions. The other starting reactant was KSCN, which decomposes to form potassium ions and thiocyanate ions. Although both decomposition

small error. And not only that but also the fact that as table 2 shows that the final amount needed was .0131 g less to the actual mount that we added from table 1. During the procedure our percent error must of have come from loosing the silver ions. After heating we had to wash the moisture of the watch glass back into the beaker and there could have been a possibility that we didn’t wash of all of the silver back into the beaker. When it precipitated, some of the particles may have peptized

The K atom will lose one electron and acquire a positive charge, so it will become a positive ion, K+. The Cl atom will gain an electron and acquire a negative charge, so it will become a negative ion Cl-. Here, we can see that KCl consists of a positive ion (K+) and a negative ion (Cl-). __Salts__ are ionic compounds consisting of positive and negative ions. Because potassium chloride has ions of opposite charges, potassium chloride is classified as a salt. !!!Uses of Potassium Chloride

conductor through which electricity enters or leaves an object or a substance. The net result of two electrode reactions added together is ( H + ions + 4 OH ions ). An ion is an atom or a molecule in which the total number of electrons is not equal to the total number of protons, giving the atom or molecule a positive or negative electrical charge. Ions can be created either chemically or physically. The cathode, the negatively charged electrode by which
