Concept explainers
Interpretation:
The relation between the chemical stability and the arrangements of electrons in atoms must be explained.
Concept introduction:
The stability of a species is reflected in the electronic configuration of the atom. Here, electronic configuration shows the arrangement of electrons in the orbitals around the nucleus of an atom.
Answer to Problem 1TAI
Electronic configurations with half filled and fulfilled sub-shell are very stable.
Explanation of Solution
Inert gases are stable because they have complete octet. Inert gases have complete shell electronic configuration.
Some atoms have half filled electronic configurations which are also stable.
For example, nitrogen with 2p3 is more stable than that of oxygen in which there is 2p4.
Thus, inert gases are very stable due to complete octet. Also, elements with half-filled outermost orbitals are also stable.

- at 32.0 °C? What is the osmotic pressure (in atm) of a 1.46 M aqueous solution of urea [(NH2), CO] at 3 Round your answer to 3 significant digits.arrow_forwardReagan is doing an atomic absorption experiment that requires a set of zinc standards in the 0.4-1.6 ppm range. A 1000 ppm Zn solution was prepared by dissolving the necessary amount of solid Zn(NO3)2 in water. The standards can be prepared by diluting the 1000 ppm Zn solution. Table 1 shows one possible set of serial dilutions (stepwise dilution of a solution) that Reagan could perform to make the necessary standards. Solution A was prepared by diluting 5.00 ml of the 1000 ppm Zn standard to 50.00 ml. Solutions C-E are called "calibration standards" because they will be used to calibrate the atomic absorption spectrometer. a. Compare the solution concentrations expressed as ppm Zn and ppm Zn(NO3)2. Compare the concentrations expressed as M Zn and M Zn(NO3)2 - Which units allow easy conversion between chemical species (e.g. Zn and Zn(NO3)2)? - Which units express concentrations in numbers with easily expressed magnitudes? - Suppose you have an analyte for which you don't know the molar…arrow_forwardNonearrow_forward
