Arrange the following isoelectronic series in order of decreasing radius:?
Al these elements have 10 electrons. So both lower layers are full of electrons. I suspect (I don't know for sure) that the electrons (or the wave function) is contracted when the nucleus has a higher potential. So the highest radius will have O++, followed by F- , Na+ , Mg++ , AL+++.
Arrange F2,Cl2,Br2,I2 in the increasing order of their bond dissociation enthalpy.?
I2,F2,Br2,Cl2 this include bond energies of those bonds. bond dissociation enthalpy is a positive value because it take enegy from the outside to break the bond
How do I arrange N, O, and S in decreasing order of electron affinity?
In an electron affinity chart the elements are listed as follows;N, 0 =or> kJ/molO, -141.0 kJ/molS, -200.4 kJ/molThe first electron affinity is the energy released when 1 mole of gaseous atoms each acquire an electron to form 1 mole of gaseous -1 ions -wikiNitrogen is actually in a positive state Nitrogen's electron configuration is 1s22s22p3 so all three p orbitals have one electron each. If you were to add another electron it would be repelledEach singly-occupied p orbital already has one electron, so that electron, clearly identical to the electron being added in every way---INCLUDING CHARGE---will repel the incoming electron, so more energy than usual is needed to add it. This extra energy needed to overcome the repulsion makes the electron affinity positive.Do your research! The more research you do the better you'll understand what your looking for and in more ways than one leaving you well rounded in the area of question.Hope this helped!

Arrange the quantum numbers in increasing energy.?
The quantum numbers listed below are four different electrons in the same atom. Arrange them in order of increasing energy. Indicate whether any two have the same energy. (a) n=4 l=0 m1=0 ms=1/2; (b) n=3 l=2 m1=1 ms=1/2; (c) n=3 l=2 m1=-2 ms= -1/2 (d) n=3 l=1 m1=1 ms= -1/2
Rank the following liquids in terms of increasing vapor pressure: C5H12, CH4, C3H8, C2H6, C4H10.?
Vapor pressure depends on the strength of the intermolecular forces - stronger force = lower vapor pressure. These are all non polar - so dispersion forces which increase with size are important - largest molecule (C5H12) will have lowest vapor pressure and the smallest molecule (CH4) will have the highest. Arrange the rest by size.
If a company’s PE ratio is less than Industry PE, or vice versa, what does it signify?
Let us first discuss first about P/E ratio:What is P/E ratio?The P/E ratio (price-to-earnings ratio) of a stock (also called its “P/E”, or simply “multiple”) is a measure of the price paid for a share relative to the annual net income or profit earned by the firm per share. It is a financial ratio used for valuation: a higher P/E ratio means that investors are paying more for each unit of net income, so the stock is more expensive compared to one with lower P/E ratio. The P/E ratio has units of years, which can be interpreted as “number of years of earnings to pay back purchase price”, ignoring the time value of money.In other words, P/E ratio shows current investor demand for a company share. The reciprocal of the PE ratio is known as the earnings yield. The earnings yield is an estimate of expected return to be earned from holding the stock.You can also go through: Stock selection criteria – follow the fundamental way of selecting a stockPrice-to-earnings ratio is popular in the investment community. Earnings power is the primary determinant of investment value.Formula:PE = Market Price per Share / Earnings Per ShareP/E Indication:In general, a high P/E suggests that investors are expecting higher earnings growth in the future compared to companies with a lower P/E. A low P/E can indicate either that a company may currently be undervalued or that the company is doing exceptionally well relative to its past trends. When a company has no earnings or is posting losses, in both cases P/E will be expressed as “N/A.” Though it is possible to calculate a negative P/E, this is not the common convention.The price-earnings ratio can also be seen as a means of standardizing the value of one dollar of earnings throughout the stock market. In theory, by taking the median of P/E ratios over a period of several years, one could formulate something of a standardized P/E ratio, which could then be seen as a benchmark and used to indicate whether or not a stock is worth buying.Industry Comparison:A P/E ratio lower than industry average reveals stock may be undervalued. Similarly a P/E ratio higher than industry reveals that the stock may be overvalued.
