Tin Tin (Sn), atomic number 50, atomic weight 118.70, is a member of column IVA of the periodic table, five elements whose outer electron configuration is s 2 p 2. Its mates are carbon (C), silicon (Si), germanium (Ge) and lead (Pb). These elements are remarkable in that they are commonly used in the pure form.

- gooEffective Nuclear Charge. Effective nuclear charge, the charge an electron experiences after accounting for the shielding due to other. electrons, increases from left to right across a given period, thus an electron in a 2p orbital of a nitrogen atom. experiences a greater Z. eff. (3.83) than an electron in a 2p orbital of a carbon atom (3.14).

- Determine the expected charge of the non-metal using the a similar procedure. Elements in column 17 (F, Cl, Br, I) have a -1 charge in ionic compounds, elements in column 16 (O, S, Se, Te) have a -2 charge, and elements in column 15 (N, P, As, Sb) often have a -3 charge in ionic compounds.The total positive charge of the metal must equal the total negative charge of the non-metal.lements in column 17 (F, Cl, Br, I) have a -1 charge in ionic compounds, elements in column 16 (O, S, Se, Te) have a -2 charge, and elements in column 15 (N, P, As, Sb) often have a -3 charge in ionic compounds.

- electrons have a charge of -1, neutrons are neutral and protons have a charge of +1. different atoms have different … numbers of protons and neutrons and electrons, but in their normal state the number of electrons is equal to the number of protons, so the charge is neutral.

- SN2 indicates a substitution, nucleophilic, bimolecular reaction, described by the expression rate = k [Nu][R-LG]. This implies that the rate determining step involves an interaction between two species, the nucleophile and the organic substrate.

Nucleophilic substitution Nucleophilic substitution at carbon. In SN2 reactions, there are a few conditions that affect the rate of the reaction. First of all, the 2 in SN2 implies that there are two concentrations of substances that affect the rate of reaction: substrate and nucleophile.

Standard Electrode Potentials The Nernst Equation. The cell potential for a voltaic cell under standard conditions can be calculated from the standard electrode potentials. But real voltaic cells will typically differ from the standard conditions. The Nernst equation relates the cell potential to its standard cell potential.

Galvanic cells and electrodes In this notation the cell we described above would be. Zn (s) | Zn 2+ (aq) || Cu 2+ (aq) | Cu (s). There are several other conventions relating to cell notation and nomenclature that you are expected to know: 1  The anode is where oxidation occurs, and the cathode is the site of reduction.ositive charge (in the form of Zn 2+) is added to the electrolyte in the left compartment, and removed (as Cu 2+) from the right side, causing the solution in contact with the zinc to acquire a net positive charge, while a net negative charge would build up in the solution on the copper side of the cell.

Difference Between an NPN and a PNP Transistor In an NPN transistor, current flows from the collector to the emitter. In a PNP transistor, current flows from the emitter to the collector. How they turn on and off is also different. An NPN transistor is powered on when a sufficient current is supplied to the base of the transistor. Therefore, the base of an NPN transistor must be connected to positive voltage for current to flow in.

- +6 for each sulphur. +1 for each Na; Two oxygens are as peroxides and will have -1 charge / oxidation number each. Six oxygens are as oxides and will have -2 charge each. So, … 2(+1) + 2y + 2(-1) + 6(-2) = 0 Or y = +6 (the charge / oxidation number of sulphur). 2 people found this useful.

- 2 Cl-Cl2 + 2 e-. The potential required to oxidize Cl-ions to Cl 2 is -1.36 volts and the potential needed to reduce Na + ions to sodium metal is -2.71 volts. The battery used to drive this reaction must therefore have a potential of at least 4.07 volts. This example explains why the process is called electrolysis.
